Facebook can be tripe or treasure, just like real life. It's all what you make of it. I know of many who don't care for it, and quite honestly, I think they decided they wouldn't like it before they even tried it. Just like, for example, some people don't like any modern car design. Therefore, they already dislike the cars... that have yet to be created.
I know a lady who tried to use FB, but she "Doesn't get it". I don't get that.... what's to get? Most women seem to like to post the "inspirational" message stuff. Doesn't do much for me. Guys just like to joke around, and sling some sarcasm. Works for me!
The one thing that bugs me about FB is the ones who think it's a contest to see how many posts they can make per day. I know of someone who must be posting 50 or more times a day, if not more. That goes beyond socializing... right into obsession!
