The internet itself is dreamed of and often described as a place of limitless and unrestricted access to information, yet so many people believe they have a right to privacy when entering into this domain. Nobody is forcing us to use the internet, make blog posts, check facebook, and post on our favorite websites. Yet we do anyway because it is an enjoyable pastime. The idea of facebook itself is one of you (the user) having special access to other users' personal information, ideas, photographs, and so on in the form of them being called your "friends". The act of using facebook is one of willingly and knowingly invading the privacy of others that many fight to protect, though they too engage in these kinds of behaviors. I know hypocrisy doesn't make an argument invalid, but I feel that so many people ignore the benefits they reap from accessing others' information as well.
What it all comes down to is this: if you don't want your information out there, don't put it out there. If you want to remain as "private" as possible, then stay off the internet and keep out of others' private matters as well. If you just can't keep yourself offline, then keep a tight lid on what you say and who you say it to, or throw some money down and use the services of Reputation Defender. They'll be more than happy to help for a fee of course.
