Check out this post for the big list, that's been going for a while: http://forums.toucharcade.com/showthread.php?t=2021
I set one up earlier in the month for Smiles news, though I haven't promoted it yet. http://twitter.com/smilesgame I also have a personal Twitter. http://twitter.com/mikekasprzak You're welcome to follow me, but be aware I probably wont follow back. I try to keep my list short and concise. Other developers that are reasonably active, former coworkers and friends I've known a while. From me you'll hear occasional progress notes, silly banter between developers, and quips about the local food joints.
