I have a couple. My personal site for music-related things is at http://170bpm.net I also write for a major tech news blog at http://thenextweb.com
I use my personal site primarily as a source for hosting and releasing podcasts of my live DJ shows. I also use the site to arrange bookings for music-related business.
At The Next Web, I am the editor of the Google and Apps channels, focusing on breaking news around tech in general.
