I've been immersed in fanfiction community for more than seven years now and I've seen more than enough to back up my claim. I have of course seen lots of awesomely written fics get bandwagons and I've been there to congratulhate them for their success. Portmanteau's ftw. I've also seen more than my fair share of awesomely written fics get left by the wayside for no raisin.
I just think that at the end of the day, would you rather be remembered for being popular, or being good?
