The film soylent green is about people being harvested for food. That's how I see Facebook. Your details are being harvested for business and advertising. Sure, it can be beneficial to stay in touch with each other, but there's a bigger price to pay. I've come to the decision that the amount of information I'm getting from other people isn't worth the price I'm paying for that lack of privacy and having my details flogged to advertisers.
So, I've made a deal with myself to give up on facebook and see how it goes for a month. I'm not going to log in or check any status updates from facebook. However, I will continue to get stuff from twitter and blogs as they really offer interesting stuff.
So, if you've stumbled here instead and we were friends on facebook, please don't take it personally, I just don't like being harvested.
