I'm someone who's only been to Facebook a few times, due to Google searches taking me there. I understand that it's a social site for people to post information about themselves and communicate with friends who use the service. I don't understand it when I see a product saying "Come visit us on Facebook!". Is this just a glorified web page? Why not just put up a website for your company, and let people link to it? Maybe it's like software APIs or something, where the company's Facebook page is a sort of wrapper that makes their interface match that of other Facebook users?
Its all about communicating with customers, and getting new ones. If you can get a customers to friend you what you post shows up on their wall and when
they friend you it shows up to all their friends. So the idea is very simple, get a bunch of people to friend you, send content out them and then get them to bring in
their friends.
Honestly with the size facebook is I would be worried about any company that was *NOT* on facebook.
