Here comes another bubble...

Facebook is grossly overvalued by any traditional measure of company value (valuation/revenue in the region of 100), but on the other hand Facebook isn't priced by the open market. The only thing supporting the company's valuation is Microsoft's 250$ million investment, which was probably more politically motivated than motivated by economics. (At a valuation like this one, which other market players would be remotely interested in investing?)
At this point, what happens in Silicon Valley isn't a bubble. Investment is under control. Certain companies are overvalued, but the valuations aren't supported by any form of mass hysteria: if anyone is burned, the effects will be local.
And don't forget that even during the IT bubble at the turn of the millennium, many sound companies were created. There is bound to be a smaller or larger degree of dead weight dragged along by any new breaking of ground in technology. This isn't a new phenomenon by any measure.
Where do you think the money is coming from? There may not be an IPO market, but Joe VC is getting his capital from individual investors and organizations that are just as flighty and nervous as they were in 1999.
All it will take is one or two high-profile failures, and it'll be nuclear winter in the valley again. The mechanism may be different, but the results will be the same.
Catchy and creative!
Anyway, still a fun watch.
