I've been following the barrage of news regarding Data Portability with a mix of excitement and trepidation. I've been a proponent of OpenID, and regularly use services like PassPack to keep track of the ridiculous number of log-ins I seem to have accumulated. At the same time, I worry about what data is essentially mine, and what doesn't rightfully belong to me. I'm still not convinced that Robert Scoble owned the contact information for his 5000 "friends" on Facebook, and that is the facet of Data Portability that worries me, at least a little.
