If you want to weaken Facebook, here's an idea. Get a dot-com and put it on a business card with your email address and/or phone number. When you meet people, give them that card. That's what I do. I keep them in my wallet. So much easier (less awkward) than exchanging phone numbers. I'm not even that extroverted and I'm surprised how many cards I give out. I always get a positive reaction to the card and never once had someone look at the card and say anything about Facebook. It's also revealing to see how different people react to the card. If more people did this, I think it would cut Facebook out of more social interactions.
