Trying Google Friend Connect

I'm trying out Google Friend Connect on this website. I'm not quite sure what good it will be, and so far only a members gadget has been included in the left sidebar. Contrary to what "Join this site" or "Sign in" suggest, it does not actually let someone sign in to this website, which means that one needs to write in names and links as usual when commenting.

For now, Google Friend Connect is only useful for showing one's interest in this website through the members gadget (and who would be interested in my little personal website?). Perhaps one of these days there will be more to be gained from Google Friend Connect, although it may also be likely that I'll give up on it eventually.
