I'm obviously all for these social networks as long as they "complement" our community/social life, not replace it. I just don't want to get to the point where I'm updating my fb profile and tweetering the night away, while I don't even know my next door's neighbor's name.

The other danger I see with these online profiles/social networks is that... I sorta don't want to be too open/honest online, because who knows who's reading it and how they'll use the information (i.e. obviously, don't put in your address, I don't even put in my real birthday date)

At the same time, I don't want to be deceitful and sorta "create an alter-ego" online. Maybe I'm just thinking about this too simplistically, but I want to be the same person at work, at church, with friends, online, everywhere. Or do you all think that's all okay & harmless?

With that being said, I've found a lot of value in facebook, linkedin, and twitter: Facebook for keeping in touch with friends and acquaintances (and reconnecting with childhood friends) Linkedin for finding people with expertise I'm looking for (some good "matchmaking for business!") Twitter for getting to know a few folks much better & finding cool-corners-of-the-internet links.
