Oh hey, I meant to send you a note about this, but you might want to check out inclusive_geeks. They tend to post about video games/nerdly things in relation to -ist issues. It doesn't have open membership (to keep trolls out), but I don't think joining should be an issue for you if you're interested.

Also, for your soft foods, have you considered yogurt or pudding? There's also creamed corn. (A friend of mine also got her wisdom teeth pulled recently, and we had to brainstorm food ideas for her.)
