Too much money in SE and related services - MSFT, YHOO, and others will invest much in this business (take overs) - so much I think google might end up as another NSCP...
But sure it would be nice to have some stocks in the company - just not AFTER every man, woman and child have invested in the company (IMHO, the IPO is the big cash cow - not the stock in 5-10 years)
