My friend and I work on a science vlog together called Brainstorm. It's on his channel on youtube: qdragon1337.
I also do ebusking on blogtv. I do piano improv, tell stories, do spoken word and shoot the shit with the chatters. My username on there is Crowbarazar. (though I haven't done one in months)
The only caveat is for musicians. Hey, if you're in the business then there is likely some music that holds personal significance to you and that's ok by me. I'm the same way, but that's not really the same thing I'm talking about up there.
