Something I know you are aware of is the fact that social networks is becoming increasingly more popular each and every year mainly because it is a fairly easy way to connect with individuals. There are many social sites, many are rather general in nature, while other sites focus on certain niches. For those social sites who don't have a specific niche topic you are going to see that there are different groups inside the site that will have common interests. Many people don't realize at this point, that social networks can be a great advertising tool for people who promote particular products.
