About a month ago I started streaming video games at twitch.tv/andreaen. I split my time there between Quake and other games, currently Arcane Dimensions and Shadowrun Returns. I'm live three or four days a week (never on Wednesday or Thursday). Time of day varies depending on my sleep schedule.
One thing I won't be doing on twitch is streaming DJ sets, at least for the near future. Mixcloud seems like a better place for that anyway.
So if you want to hang out, watch some video games, maybe talk about how heavy records are, twitch is a good place for it.
