I quit Facebook Mon, 31 May 2010
I decided that having a Facebook account primarily for extending the marketing/publicity for the work that I'm doing wasn't worth it. I disagree with Facebook's "public by default" policy and the way they roll out changes to their Terms of Service and privacy settings. I think their recent change to make the ui for privacy settings easier to use (and not require a phd) is a good one, but not good enough for me to feel comfortable giving my data (or that of my friends and family) to them.
I'm also in the process of signing the copyright assignment statement to join the GNU Social project to build a federated system that gives people full control over their data. I'll be looking into building these features into PyBlosxom, as well.
