I had many people ask me about Friend Connect when I put it on my blog as part of an early beta, so I figured I should post quickly about it again... While it's been pretty cool up until now, there were only a few blogs which had it - so a bit less "connecting" on my blog. But now, anyone can add it to their site.
If you haven't noticed it, or don't even know what I'm talking about - it's those to little windows (gadgets) on the right side of this blog. The first shows people who "follow" my blog, and the second provides a place to quickly comment on the blog or on a specific post (comments on a specific post page are separate from other comments).
Check out the Friend Connect blog post to get the accurate info.
