I was recently asked why I stopped using facebook. The reason I closed my account is because I got sick of people poking me all the time and being attacked by zombies etc.. what a waste of time. The other reason is, I looked into who actually owns facebook besides it’s brain child Mark Zuckerberg. For example, who has supplied funding and who owns a piece of the company. This Article at tribes provides some good information on the people who have bought a piece of facebook.
There are also privacy concerns and identity theft issues with social networking sites that I find a little un-nearving. However, I have a profile on linkedin so I guess I am open to some of these concerns as well.
