Well it looks like I'm late to the party. Copy+Paste from another post. - - - - - - 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.

My personal twitter is: www.twitter.com/matt_tighe It's mainly concentrated around my iPhone work, most of which at the moment is games with Megadev.
I started tweeting at http://twitter.com/blikstad but I'm imagining it will turn out pretty random eventually... both in subject and frequency. So, follow at your own risk.
I'm going to start posting more about iPhone dev at [ http://twitter.com/azumanga ], or at least, that's my plan!
Yeah, count me in. Decided to start adding stuff daily to mine I will be posting free codes to my stuff from time to time too. http://twitter.com/Lazrhog
