See: The State of the Facebook Platform | 20bits. The number of active users has declined 27 % since January. Early adopters are leading the pack out.
I deactivated in December, 2007 (See: “I deactivated my Facebook Account, is LinkedIn Next?“), reactivated for a few days earlier this year, and then deactivated again. For good.
I did cancel my LinkedIn account, too. As I discussed in a post about it, if everyone has their own blog and RSS feed we can just communicate through those.
And I still think every patient should have a blog that their physician has access too through the electronic health record.
