That's a little cynical. Maybe not completely wrong, but I'd like to think that people are able to judge a fic more than it just being something in vogue. If it's well written and tells a good story, then I think that it has a good chance of at least gaining some steam. It may not be earth-shattering, but it certainly can pick up reviewers and followers if it updates frequently and is of a high quality.
Hell yeah it's cynical, that was the entire point of my post.
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?
