Can someone tell me what is facebook?

It is a little easier to use than Myspace and much less cluttered, it's better for close friends and relatives ect, also much easier to find people you haven't seen in years. One downfall is people can see almost literally everything you do, for example, me and you are friends on facebook, you comment on somebody elses page and it comes up on my homepage of what you said to them so you have to be careful of what you say depending on who you have added
I always used myspace and hated facebook until around a year or so ago when I started getting into facebook and now I rarely use myspace, like I said before, facebook is a lot easier to contact friends and family and is a lot easier on the eyes, just takes some getting used to is all.
