I love FB for all the reasons Sandra and LouAnn stated. Also, you can join "groups" ... for Newfs, Goldens, Politics, Rescue, Military, the NCA, Geographical-specific, College-specific, Work, and on and on. There are areas for anything and everything you might have an interest in.
And then there are the addicting games.........Farm Town, Mafia Wars, Mouse Hunt, Farkle, just to name a few. hahahahaha!
I really hated MySpace. WAY too busy (as in movement via pics, videos, music all over the page)...noisy...etc. FB is very different - and clean looking. I've connected with people I haven't seen in years.
Georgie...in the right hand upper side of your page, there's a link for Settings. Click that and look at Privacy Settings. See what you have blocked (a reddish circle with a line through it). You might want to unblock some of those things.
Leonard...FB does have rules, but you really have to push the limits to get warned or kicked off. People can complain about "content" ... but often it's just because they disagree, not that the user has posted anything wrong. You can state any opinion you wish, including videos, links, etc. If someone doesn't like it...they're free to disagree, if you've made those comments public (or even public to just friends). If you don't like them or the way they're responding to you...you're free to block them from posting on or reading your comments/page.
