Here's an interesting article By Edward C. Baig, USA TODAY.
I found it interesting because I've come to believe that Facebook, far from being the superficial touchy-feely fad it appears to be on the surface, has quite a bit of value to offer people who are interested enough to think it through and personalize it.
Here's what Baig has to say:
•Finding friends. Face it, some people collect friends like baseball cards. (Guilty as charged.) I'm approaching 900 pals; 5,000 is the max.
But not all friends are created equal. Mine may represent a typical mix: distant and close relatives, neighbors, current or former classmates, camp mates, co-workers, industry contacts and bosses.
Frankly, there's a voyeuristic appeal to the idea that you might get to rub elbows virtually with a celebrity. Actor Philip Seymour Hoffman was my Facebook friend for a while, until I was unceremoniously dropped. You aren't even notified when someone gives you the heave-ho.
I typically expand my social connections by searching friends of friends. If you don't know the person well or at all, send a brief message telling them why you belong in their inner circle. I see which friends we have in common before I accept a stranger's invitation.
If you want to be found by old comrades, consider allowing people to see your list of mutual friends, even if they're not connected to you. That way they know you really are the John Doe they went to high school with. But letting people see your friends is a double-edged sword: Your friends may not want people they don't know hounding them.
•Private matters. Facebook has been described as a party where you need to assume the entire room can hear you. Learn the terminology. Wall-to-wall posts can be seen by others. Send a private message if you want to keep an exchange under wraps.
Familiarize yourself with the privacy options, found under "Settings." You can determine who among your network (friends only, friends of friends, etc.) can view your user profile, personal info, status updates, photos and videos tagged of you, friends lists, wall posts, and education and work information.
It's also a good idea to group friends into customized Friend Lists, perhaps one for professional contacts and another for school chums. You can apply different privacy settings to those lists. Your bosses need not relive your college exploits.
Generally think long and hard about the information you reveal in your profile, from the year you were born to political or religious beliefs. But you're likely to get as much out of Facebook as you put in, so withholding too many details may be counterproductive.
One of my Facebook friends, Roger Matus, CEO of e-mail archiving company InBoxer, recommends three tests before posting: Would you be upset if your mother saw it? Would you be upset if the most nefarious person you ever heard about saw it? Would you be upset if it was on the front page of USA TODAY?
It's all a balancing act of sorts. What good is a social network if you're too timid to be social?
