Next: I happened across Twiddla.com yesterday, which is a free sharable web-based whiteboard that lets you doodle on or annotate web-pages with others in a chat room.  Highly amusing, and probably useful too.  I seem to remember something like this coming out a year ago–a tool that added chat to every webpage, but I don’t remember what it’s called, and haven’t seen it since.  Guess it wasn’t that successful.

I’ve also been making myself familiar with the work or dataportability.org, promoting open standards for data sharing.  I especially like OPML for its simplicity and usefullness (I’ll be sharing a big OPML file here soon), and hope that APML includes an element for sharing one’s OPML along with your other social information.
