rating - SNS

I have joined some social network sites.
Yesterday, I joined a new SNS. My friend sent me an invite mail like many other sites do so. I enjoy the site.
I'll join other sites later and will re-rate then.
Okay, so here is my current rating of social network sites which I've been online.

Myspace ★★☆
I don't like it because there are so many spams there. My page isn't a free ad place.

Facebook★★★
Logga in Everyday.

Tagged★★☆
I've got some good friends on this site. And of course got a lot of junk msg from kind of perverts same as other sites.

Hi5☆☆☆
Uh.. I can't see even one good point on this.

My Yearbook★☆☆
This real chrities idea is nice. But that's all.
