My grandmother invited me to a group that says that Facebook is going to start charging 15 GBP/month unless that group gets 300,000 members. It seems that some company is looking to buy Facebook and start charging for it, but if 300,000 of Facebook's 200 million active users say they aren't willing to pay, that would force them to keep it free.
My grandmother also sends me a half dozen guardian angels, dogs, farmville gifts (which has nothing to do with Farmville, which I don't play), etc every day. These things are nothing more than a little icon. Until my grandmother joined facebook I think I blocked one or two apps, and I've had to block about a dozen since she joined. Eventually I may just have to block my grandmother. She doesn't really "get" the Internet. She sees her role on the Internet as a middleman. If she receives an e-mail, she forwards it to everyone she knows. If she gets something on Facebook, she passes it on to everyone she knows. I'd be scared of what might happen if some unscrupulous person tried to scam her, but she has no money to steal.
