This is one of the things I miss the most, actually, is the daily shot-in-the-arm of inspiration. My artistic ability thrives when surrounded by creative input, and tends to flounder when left in isolation -- which is a major reason I'm such a con-hound. So I've been looking for an alternate place to find that fix.
Artvark, alas, is officially "retiring," so that is kind of a wash. YNA seems to be picking up a bit, so I'll be checking that regularly now. I try to check out DeviantArt periodically, but the navigation there ranges from "incredibly confusing" to "completely incomprehensible," with occasional stops at "INTENSELY FRUSTRATING!!!" ... so I tend to avoid it. (Wow, I miss the simplicity of Yerf!) Too bad, too, 'cause there's some nice stuff there. VCL, of course, is not browsable at work -- and only barely browseable at home without my eyes melting. (Thus, I'm grateful to people like doodlesthegreat who post "VCL Picks of the Day." Speaking of which, happy birthday, Doodles!)
There is also furryartists, but that tends to be more "I have an auction up!" announcements than actual art posts -- and even those are only two or three a month.
I know there's still art out there being made, and good stuff, too! It's just a matter of finding it.
