Not everyone has one you know. I had to get a FB just to get coupons, but don't use it for anything else. Twitter is for folks who have no friends. I don't need to know that you went to the bathroom and the TP ran out, or that you think Mimmie MooMoos has the best Fried Burgers.
Twitter is for people with no friends? lol Get real. And if you know people who would tweet that they ran out of toilet paper, you've got some strange acquaintances. Sounds to me like you're just resistant to adopt new trends. There's nothing wrong with that - do what you like. But there's no reason to insult those who do take part in social media. It has a lot of benefits, just like bazar6 said.
Thank God I never changed my old Alltel unlimited data plan.
