It's on. Read the prospectus, get a bidder ID, and watch a Meet the Management video.

Simplifying things dramatically, and playing with a little math, if sold at $135/share... Google will raise $3,325,948,965.00. Does that strike anyone else as quite a load of cash? What will they do with all that? Honestly. It could be very strange, or very exciting looking ahead for Google.

I'm no investment guru, but browsing through the prospectus, I see this claim about what they'll do with the $3 billion+

We intend to use the net proceeds from this offering for general corporate purposes, including working capital, and possible acquisitions of complementary businesses, technologies or other assets. We will not receive any of the proceeds from the sale of shares by the selling stockholders.

And they'll still have 268,519,643 outstanding shares.

Here Google revenues from 1999 to 2003 present:
$220,000 1999
$19,108,000 2000
$86,426,000 2001
$439,508,000 2002
$1,351,835,000 2003

Pretty nice growth curve.

Anyway... fun to read the prospectus of a company you feel like you know a little about, and that you care about.
