I'm thinking now about making a variant of Crowmask that pulls posts from DeviantArt instead of Weasyl. It would simplify some things (all posts have GUIDs) and I'm more active there, but I would have to add an OAuth login flow.
I wonder if I should call it Crowmask 2.x, or give it a new name? I'm leaning towards the former.
(I'd rather not have one codebase that pulls from both - there's not much use case for it.)
