Google used a "Dutch Auction IPO" to release it's shares last week. I think they hit the street near $80 USD and were somewhere in the $100 USD range last evening.
Notwithstanding the fortunes of this particular stock, it's significant that the auction took place. Following the burst of the "tech bubble" in 2000. More on IPO from the contributors of @ wikipedia.org
It's also significant in that Larry and Sergey were able to take Google from a concept to a popularly used verb (not to mention a company worth ~ 35 billion) in six years.
Speaks to power of ideas and the web as a medium.
