Google Friend Connect
I'm experimenting with Google Friend Connect as you might notice from the new gadget over on the right. Feel free to join up, but as it's just an experiment there's a good chance I'll be removing the feature in a bit. I'm thinking that with the addition of a couple of OpenSocial event management gadgets a Blogger blog might be a good, non-Facebook alternative for organizing an event, but we'll see.
You should follow me on twitter here.
