I'm genuinely curious about which site is their main other than FA for now. I use this site but I only generally see activity when FA is actually down. Furry Network got a big initial following but I'm afraid to join that in case it also drops off rapidly in terms of activity.
What sites do you main?

Me personally, lotsa places.
But the only 'furry' type places you'll find me are FA and Weasyl for now.
Generally I use tumblr as an art-blog more than any given art site for my personal work.
FA and Weasyl are mostly commissions :)
