After beging invited last night by Chris to his “Friend Connect” widget on his blog, I also decided to give it a go.
Another social networking tool …. let’s give it a try as well. So I added the widget(plus some additional installation instructions) onto my website.

(as seen on the right hand side of this blog)
For more instructions on how to get it setup, you can read Chris’ post about Google Friend Connect.
One downside I found when inviting someone to join is that they come to your blog, but they don’t exactly know where to go next. You must actually explicitly tell them in the invite comments that they must click on the Join Side button on the widget, expecially if they are new to Google Friend Connect.
