you can't add people as friends in blogspot but you can definitely have the page of your friends or at least those whom you know who also uses blogspot linked in your page through some programs... that thing i don't know how to do... hehehe... i also have a blogspot of my own... Blogspot is a more private place as long as you don't disclose your address.
So i guess you won't be alone anymore since you just announced the page. hehehe
