Someone could read what you wrote and buy stock when your actual reasoning is simply because you think the public are going to get excited and buy the Facebook stock because they use it, along with the big assumptions that a) this wont already be reflected in the price and that b) these people who are buying the stock will have a meaningful impact on a $100b cap company with a 'significant' increase in price.

These are not the best assumptions and reasons to state that it's highly likely that FB stock will significantly increase. Every time I hear someone say something like this I have to ask how much of their own wealth they've stuck out on the line because more often than not it's nothing.
