I've been playing with Ning, Gather, and other social media sites. You can come join me if you like.
I've added a couple of widgets to my sidebar. Scroll down and you'll see them on the left. They are simply RSS feeds, but made a little more attractive, perhaps.
You can subscribe to a feed for this blog, too. (Not that I ever have time to update it, of course.) If it seems to work, we'll consider adding a similar option to our College's news blog.
