I just joined Facebook about 4 months ago. I had never done the MySpace thing.
It has served it's purpose, In August the summer camp I went to 25 years ago had a reunion and Facebook is how we all connected. I'm now on Facebook multiple times a day. I sort of equate it to texting instead of actually making a phone call.
I haven't had a single problem with stalkers etc...
All of the virtual sending stuff is a bit juvinille ,but then again so is the internet. You don't have to pay for anything, it's your choice. You can send free "pokes" or "flairs" or whatever ya want.
