Facebook, the only social networking site that I profess to like is now opening its doors to the general public. I logged in today to see this invitation box in my face asking me to invite my friends. I did not. I like Facebook for its exclusivity. If I wanted the whole world on my friends list, I would have joined MySpace. Mark Zuckerberg is looking to sell Facebook for a cool billion after which we’ll be inundated with marketing ads. I’ll sign off right then.
