Social network

What do you think about it?
Do you use Facebook, MySpace, Netlog or what?
I'm a bit confused about social network. Is it really what we need?....

I don't like them.

in my opinion netlog etc.. are useless

I think social network are good sites for serching new friends. I like them. I use facebook and netlog. I`ve got a lot of people that are my friends on netlog. I`ve been using netlog for a long time.

Sometimes I use Netlog

I think that these sites are very nice and funny...

I use facebook and netlog... But facebook is more serious than netlog...

I think social network are good sites for serching new friends. I use Netlog and Badoo. But for enroll to Badoo you must be over eighteen. But many people under eighteen are enrolled there..

Double post

I think social networks are a good way to stay in contact with friends that travel around the world.
For example I have a friend who is attending his Erasmus in Germany and he stays in contact with his italian friends with facebook, posting some photos of the place and his new friends.

In my opinion, that kind of site is not best think to found an new friends . But also it can be nice way to meet person from all world or country and talk about our interesting, politics or something else .
So, all in all this kind of site can be usefull but we cant build our social relationships only using this way.
