Facebook has definitely made its mark as the top social networking site. Statistics indicate that there are now more than 800,000,000 FB users now and continues to grow. I know! That's a lot of zeros. The popular social networking site is also used for advertising products and services too which is expected as who would not take advantage of the large number of users as potential customers or clients. There are plenty of fan pages that offer their followers freebies and discounts. I saw one page that indicated a 20% off through proflowers facebook page. Well, who would not take advantage of an offer like that?
