I deactivated my very minimal Facebook account today. Haven't had the time to figure out how to use this site to serve me and it was a constant "have got to get back to" hanging over my head. So long to my one friend!
Still on MySpace, in a very minimal way, to gain access to my sister's site.
Still on LinkedIn. I am slowly building connections and am seeking local connections to build a network in my immediate and surrounding area. This is a site I can see potential in and will continue to work with it as I can.
I still blog. It works for me and I will stick with this for a while.
