I'm interested in Facebook.

Yes indeed Facebook is very interesting, even we can meet our old friends who had not been a news thanks to facebook

Facebook is just a tools for relationship and know each other.You will more interest if used facebook for your business,for example promote your product or your blog.If you have lots of friends there,so why not? Facebook sometimes become useful on the right people,but sometimes become useless on wrong person.I mean there are many peoples who used facebook for crime or upload bad pictures.Facebook have no rules,so everyone is free to upload anything.

So you mean to say you have no other way as sharing pictures and chat with your friends as fb? That is hard to believe. BTW fb is also great if you want your private life be open all over the world, to scold at people, to dump your whole private life and fights with friends and relatives etc all over the world. Personally I find it one of the most boring sites there are. I also can't say that I need it to chat with my friends or share pictures with them. There are plenty of other ways. But if you are interested then why don't you join? Would advice your profile private (since you want to use it only to be with your friends). Better read over here but elsewhere on the internet (plus news) how and what kind of problems people have to face too if they start of have fb. A warned person....
