Many thanks to this article: How do I delete my Facebook account? … personally i am of the opinion that it should be easy to remove yourself from any website, whenever you like, with no questions asked. I believe that cultivates trust in the site. Facebook make it extremely difficult, but it's nice to know it can be done.
I'm not yet sure whether i'm going to do it. I don't really use Facebook at all, and it's always nice to simplify my life a little bit by removing unnecessary things. Besides, you never know what they're secretly doing with all your personal data. I recently removed myself from LinkedIn and felt a huge relief for doing it.
