One of this site's unspoken functions is to serve as a testing ground for new technologies that I intend to add to other sites for MIT and for my consulting clients. This morning is a great example of that: first I added a custom Google search to my site (now accessible at http://www.geoffreylong.com/search) and then, having ironed out the kinks there, added one to the GAMBIT site at http://gambit.mit.edu/search. That's the tip of the iceberg, though – last night I also upgraded my own Movable Type Pro install to 4.23 so that I can tinker with things like Action Streams, Facebook-enabled commenting and Twitter notifications. Philip, if you're reading this, consider it a preview of things to come! :)
