If you’d like to hang out and chat with other members of the Maccast community during today’s event I’ve set up a live chat here.
The system is an IRC based chat and uses a Flash based embedded client (which may take some time to load), so it requires Flash to be installed. If you prefer, you can also connect using an IRC client of your choice to irc.geekshed.net port 6667. I use Colloquy on my Mac and they have an iOS version available. The channel(room) to use is #maccast.
