The main question is how will these companies grow?
When google went public everyone thought it was overvalued, because the perception at the time was they were top of their game, and had nowhere to go. Of course they proved everyone wrong and became so much more then they were. Google is a great example of a software company using a public offering to help expand the company.
So the the question is, which of these companies can become more than what they currently are. What does Facebook need cash to accomplish? Can Groupon push in to every continent? Can Twitter become more than a microblogging service?
Considering that Google doesn't pay a dividend and has only had around 25% revenue growth in comparison to Apple (71%). I would say they haven't proven anyone wrong yet. People have bought up Google and sent the stock price soaring, so it was a money maker for people who speculated on whether people would keep buying it. But stock market pricing and underlying stock value as it relates to the company are often wildly disconnected. There are companies which dwarf Google in profits, revenue and dividend whose stock price is in the 20s or 30s.
