Facebook:

Facebook is not the first social network but it is the most popular one. There have been many other social networks before Facebook and while some of them were popular at some point in time, none could reach the popularity of Facebook. In addition to keeping in touch with your friends, Facebook can be (and is) used for business. You can use it to promote your products and services, to acquire new clients, or to get traffic to your site.

Benefits:

• Your profile is your major weapon:
  

As with Twitter and any other social network, if you don't make your profile interesting, you will hardly become popular. Give enough background information for you and don't forget to make your profile public because this way even people, who don't know you, when they encounter your profile, they might become interested in you and become a supporter of yours.
