i think a big change weasyl could make that would make more folks want to use it is to improve folders. you can only put an upload in one folder on here, while other sites (especially FA, the primary competition) allow a single upload to be in multiple folders. i just don't even bother with folders on here because they don't suit how i organize things!

Agreed on that front. I'm no fan of InkBunny but one killer app they had for my money was pools. Not only could a submission be in as many pools as you liked, you could sequence them within the pools to create a better context than just the order of upload. That and multifile submissions. Really wish those facilities would be available on basically any other art site
