Pretty much exactly what it says on the tin.

I hate the way FA deals with writing uploads, I love weasyl's collection's feature, and I happen to know that weasyl and Bleatr.com are going to be integrated at some point in the future. Given that weasyl is just so much better from a technical standpoint, I want to abandon FA all together and just go here.

Problem:
FA has momentum and that's really, really, really hard to overcome.
