As I posted below (and seemingly got downvoted for it), "Never had one, Never will"

The people I want to stay in touch with, I stay in touch with. Those I don't, I don't.

It really is that simple. You don't need facebook, or anything else, to stay in touch with the people who are important to you.

I call shenanigans on anyone who thinks facebook is a required part of life. Or Twitter. Or any other "social network" for that matter.

If you use it and enjoy it, that's great for you. Keep using it, keep enjoying it.

I'll stick to emails, phonecalls, IMs, and text messages. Hasn't failed me yet.

I'm one of them. I asked this same question in my team a few weeks ago: I got very similar sampling. The team is composed of 7 hackers (native code, embedded speech-related software). In other words, I tend to believe the results we're getting so far.

Me too. Only way I would be a member is on a dedicated Virtualbox guest. *.facebook.com is not allowed to store cookies in my Firefox.

Nope, never had one. No Google+ so far either.

I find Twitter both entertaining and useful and a little LinkedIn is helpful to keep up with old coworkers and such.
