CAPITAL LETTERS have been used since thousand years ago by Romans in order to capture moments of history with their heroic attempts, plus as symbolization of "grandeur", "pomposity", or also "aesthetic seriousness" (Luna, https://newrepublic.com/article/117390/netiquette-capitalization-how-caps-became-code-yelling).

On typewriting, Caps Lock button has been invented to help "Shift" button function on creating capital letters. This does help in making essay titles that requires all capital letters without holding your "Shift" button longer while doing the letter typing at the same time. But apparently, some findings have been discovered that some internet people can abuse it as a form to "yell" or "shout" around mostly social media. Mashable.com (2012) did an article from @CapsLock statistics in regards to sentences with caps usage. Aside of that, it also cited that apparently a paragraph full of caps lock will be harder to read compared with normal paragraph (ref: http://mashable.com/2012/08/13/caps-lock-infographic/#NnpIBHEU2uqR).

A blogger/journalist named Kashmir Hill once did an experiment using Caps Lock for her status on Twitter in a week. Because of that experiment, she got unfollowed by good amount of followers and some stated that she should stop "shouting" or even showed her the Caps Lock button location (ref: http://fusion.net/story/42057/caps-lock/). Both mashable.com and Hill's post also showed a legit example about Oprah Winfrey using caps on her very first Twitter status in which then getting some replies about her Caps usage (like this and also this <- quite ironically this guy also uses capitals on his Twitter name as well).

There's also one (or maybe there are also some) case which shows Caps Lock usage can attract fair bit of people in positive way. Hill did another similar experiment by re-posting a link with the same caption with a week gap. She used small lettered captions along with the link on the first week, but then used CAPS LETTERED captions on the next week. Here's the result:

To prevent this, some keyboard makers decided to remove the Caps Lock key to be exchanged with another button which usually acts as secondary button. On this case, Google Chromebook CR-48's Caps Lock button is replaced by "Search" button - same to Colemak Keyboard with their secondary "Backspace" button.
Based on these explanations in regards to Caps Lock usage, I have some certain fair amounts of questions for you guys:

1. What do you think about Caps Lock key abuse around internet?
   
2. Do you have any kind of impressions of people who are using Caps formatting on daily basis? Be it in social media, livestreams, or chatting applications.
   
3. Do you think Caps Lock key usage has any relation with addictive internet usage? Studies show that people with addictive internet usage has higher level to be much more emotional when reacting to things compared to those who use them on standard timing (which is around 27 hours per week according to telegraph.co.uk).
   

Answers and another opinions regarding to Caps Lock usage abuse on social media (or most possibly another place too) are welcome and much appreciated.

caps lock key abuse makes me feel insecure and vulnerable. when i see someone using caps lock all the time i know for sure that they are a very serious and very dangerous possibly insane individual. caps lock is like a dangerous meth drug and it should be kept off the streets because of how addictive and dangerous it is. i don't even use the shift key because of how dangerous and angry capital letters are.

I feel like your thread title and actual content are completely different subjects honestly.

Thankfully, one of your links (the first one) already discussed why Caps DO equate shouting. Caps were used more often for the use of inflection, just as were italics, bold, underlines, etc. They were used to differentiate tone and inflection via text which is difficult. In a sense, this is like asking why question marks make us inflect and emphasize the ending of sentences when speaking a question, or why we enunciate words that are italicized.

Caps Lock just seemed to take a life on it's own when Internet culture developed using Caps Lock. Caps Lock thankfully does exist, because inflection is very difficult to portray through text. Anger and frustration should also be allowed to be expressed. All these dumb campaigns attempting to ban Caps Lock are silly and childish. The misuse of Caps is entirely subjective and your exposing yourself to the wrong types of content if you find yourself constantly bothered by it. Hanging around anonymous forums and communities when being sensitive to obnoxious material is no fault of the Internet, but a fault of you for having poor judgement skills. I don't go to a rock concert knowing I don't like rock, and then make a petition to ban rock and roll because I didn't enjoy the concert I went to fully knowing what could happen. And the anomaly cases where there is accidental Caps Lock usage is negligible and not incumbent upon everyone to inconvenienced or modified. Personal incredulity isn't compelling for social change.

Caps Lock has certainly changed overtime in the Internet and in just general popular media. It initially started as a way to inflect better, then developed into a way of shouting, then a way of showing urgency (often in titles, headlines, etc.), and now has just become a way to display eye-catching things. You can find this modern usage of Caps present in many mediocre content creators, ranging from BuzzFeed, to those garbage social experiment video creators, to just general money-making sinkholes that you find.

Personally, I find Caps now just to have evolved into a way of attracting people when you're entirely devoid of substance and meaningful content now and has no real significance or meaningful standing. Caps are hardly used in most conversation now and general pysche and vernacular has just evolved away from Caps. A good majority of the people still using it don't have any other way to harness attention, similar to those advertisements where they write shit like, NEW FATBURNING PILL PUTS FITNESS TRAINERS OUT OF WORK!!!!! or some shit. Content will often speak for itself, at least to your target audience. But when your content is often vacuous and devoid of it, your audience will often be as well. So instead of having your audience seek knowledgeably and in a learned fashion, you rely off impulse decisions.

(That last paragraph turned into extreme derailment and nonsense)

I don't really have an opinion on the last one. I think people are too diverse to answer that. I mean, Caps Lock is often the LAST signal of someone exhibiting improper psychological behavior. You don't need Caps Lock to let you know that.

Caps locks gathers more attention, but can also make you look like a fool. Sometimes a funny fool, sometimes not a funny fool. Smosh uses capital letters for their video titles and they're funny fools. That's a compliment. So to answer your question, yes.

HI MUSTIKA!!!

Caps lock is less about shouting to me than it is about a 6 year old shouting.
But hey, there are times when it's needed, like if you're ins chat room and need to direct people's attention to something.
But if you want to shout and be taken seriously JUST USE THE FUCKING EXCLAMATION POINTS THAT'S WHAT IT'S THERE FOR YOU BIG FUCKING FAGMOSEXUALS

FAGMOSEXUALS

A breakthrough in shit-talk technology.

Well I often see capital letters as a cheap way to get attention. Either in an article with capital letter tiltles or people shouting in posts. Capital letters can also be used for emphasis instead of shouting and I see no problem with that. Beside the caps lock abuse argument seems a bit silly to me.

Smosh? Funny?!!! HAHAHAHAHAAHAHA!!!!!!:o

CAPS LOCK IS CRUISE CONTROL FOR COOL

Lol seriously Mustika, why are you doing this much research into caps.. You know we live in an age where mimis are actual posts.

I bet most of you cant even write well because most of you can type on a keyboard anyway.

Caps lock is an anagram of cockslap.

Because I sometimes love doing researches from simplest thing in regards to human behaviors and activities that piques my interest, am kinda being skeptical at the moment (which is hopefully not in that wrong direction), and I even was hoping that I could find any study from this Caps Lock. But not much.
I'm quite aware that most people here are internet experts, which is why most of you wouldn't mind if you find any Caps in it.

I asked some older people about this (that are only use chat applications and sometimes visiting on Facebook), and it appears that they do think that they have this fixed perception that Caps Lock users are rude or blatant. Externus did get the points about anger should be thrown somewhere and you can't expect people to understand "how bad caps lock usage abuse really is", but some people have other different ways to vent it out without involving others (e.g. meditation).
I'm also agreeing to Person McPerson that caps usage can be funny too. There are plenty of funny videos I've watched that use caps and they kill the "caps are evil" impression, in a good way.

Taking that aside bit, I personally am in the middle of both sides (between statements that "caps are bad" and "caps are OK + shouldn't be taken that seriously") when it comes with forum communications. I still do use caps when wanting to emphasize things, mainly when there's no bold, italics, or underline options. But then it's actually personal preferences and I'm quite aware of it. I simply want to know how much CAPS can affect people's emotional state when communicating with others, and also reading the whole full paragraph in full CAPS compared to do it with normal formatting.

Here's kind of Caps usage example which I should probably address at the beginning of this thread (and since most of you don't mind with caps then I guess I don't have to put this on spoiler):

LIKE, CAN YOU READ THIS WITHOUT FEELING OFFENDED OR TAKEN ABACK BECAUSE I JUST LOVE USING CAPS AND I READ BETTER THIS WAY THAN USING NORMAL LETTERS? I THINK THERE ARE CERTAIN PEOPLE THAT GETS EASILY ANNOYED OR MAD AT THE CAPS USERS DUE TO UNKNOWN REASONS. MAYBE BECAUSE THEY'RE INEXPERIENCED OR JUST SIMPLY HAVE MORE EMOTIONAL SIDE ON THEM WHEN READING IT. I CAN'T REALLY GIVE MORE EXAMPLES THOUGH BUT THIS SITE SHOULD DO THE MOST EXAMPLE THAN THESE FOUR SHORT, YET INTERESTING CAPS SENTENCES.

Then compare with this:
