Since getting a Motorola Droid and downloading the Ustream app for it, I have started streaming again. I typically send out a tweet on twitter when I am going to be streaming. I used to do Rock Band score runs on here a long time ago, but now I stream lots of random things from Rock Band to other hobbies to my real band.
