To favor or against

Facebook, msn, fotolog, blogg...to favor or against?

Actually, everybody have these blogs or webs. But, is it bad or good?
First, I'ts true that shy people can relate more easily and make friends. It is also a good way to talk if the ohter person lives far away. Through fotologs or blogs with arthistic people, can give free rein to their imagination by writing something os hanging pictures.

Facebook, for example, is a good way to find people that you didn't see for more time.
And in the other hand, there isn't way of knowing who is the person you're talking. I am talking about children abuse, or pedophilia, or the same young girls who have been raped or killed, having been with anyone to see each other. Furthermore, relations through a computer screen are very neutral. Shy people, tend to isolate themselves, preferring to talk on msn before going put . People can depend of these media. In conlcusion, is a good form of communicate but be careful!
