I sold a couple commissions a few months ago...I can't say whether that means anything though, because my average is 1-2 a year...^^;
I don't think the market is dead, though. Standard art commissions run 30-50 USD, and people who have that kind of money to spare on a regular basis still have it, as far as I can tell.
And speaking of dead:
...I don't understand why people say this. =/ I've gained more followers on Tumblr in 5 months than I have in 2 years on Twitter. And I know that doesn't automatically mean the site is buzzing, but for a newcomer to be able to pull numbers like that, it can't really be dead, can it...?
Furthermore, most of the people I followed from Twitter onto Tumblr are equally active on both sites. Maybe the site isn't as alive as it used to be (?) but it's far from a ghost town; and I hope anyone who's considering branching out there understands that.
