Okay, I'll bite

Big Brother has shown us two things:

1) you will always find dumb fucks prepared to make fools of themselves in public

2) the marketing for advertising around such a format is limited.

Caveat IPO-investor because you are the dump part of the carefully orchestrated pump-and-dump scheme that is Facebook. While Facebook is making a profit a price to earnings ratio of 100:1 is fucking insane (see the Schiller average) and costs are only likely to rise from here-on in. Buying at that price can only disappoint as further share price growth is beyond the realm of fairy tales and dividends must be paid from revenues. Those are the two main reasons for investing in a company.

Amazon is good historical comparison: anyone who bought stock on the IPO is still waiting to recover their money.
