I feel like there may be a "Look at me!" element with some of the people here, but fame would be a misguided reason for joining. I'd give you improvement or showcasing your skill, but I don't think outright fame.
For the most part, I see that as something that just happens as a result of all the hard word and time that goes into what they're doing, even if the fame itself is relatively clique.
ya your right, but i think that there might be people who want to be looked at without even putting in hard work and effort - kinda repeating waht u said tho
