Friendster, MySpace and now Facebook offer a different kind of interaction today and a lot of it is attributed to the fact that people want to meet new people or hook up with their past friends. Social networking sites come in different groups and today, most people have found themselves patronizing the most populated ones like these three mentioned sites.

As a perk, some of these sites have allowed applications to become their marketing niche. Some use games while others provide different applications that allow them to enhance their sites as if they were actual websites. The clear advantage here is if you are above the rest, then chances are you have taken most of the market already.
