Yes and no. A lot of people actually get roped into the online games like Farmville because your success in the game often depends on what your friends playing the game do. I read an excellent explanation of this a few weeks ago. The person got invited to play Farmville and didn't feel able to leave without hurting their friends. I know it sounds ridiculous, but it was from a journalist and was very convincing. I don't know how many people are on FB only for the purpose of getting friends off their back, but I suspect it's a decent sized number. If so, you're not going to make much money off of those people. Another thing to keep in mind if you're an investor is the fact that technically, if you use the SEC definition of what constitutes a "private company", FB hasn't been "private" in a while. The SEC requires companies with more than 500 shareholders to go public. FB got around that rule by selling shares to corporate entities that then repackaged the shares to sell to investors. I may have some of the details wrong, but the bottom line is that a lot more than 500 people have an existing financial interest in FB (other than just employees) and those people stand to make a lot of money depending on how the IPO is valued.
