Google Friend Connect , Blogger and Reader

While lots of people are discussing about the social feature on google reader , i find out some other thing that Google trying to be social.

Firstly join any website/blog that having Google Friend Connect Feature , example the php princess blog that make me discover this.

Once you join the site you can manage it on Blogger Dashboard. Which not only manage your blogspot blog , it allow you to manage the site that you join.

If you have a google reader account, you will find out this blog already appear in your google reader

I m not sure is everyone aware on this, just want to share with all the google fans out there. I wonder will google wave be the one to combine all these tiny feature in one ?
