With LinkedIn ipo and bubble talk everywhere I can't help but notice the reality is being drowned with all these nonsensical arguments.
Personally I thought 2x increase was bit too high, then I found this article:

Firm......................Date..............First-day gain
VA Linux................12/08/99........698% Exodus Commun....03/18/98........637% Theglobe.com........11/12/98........606% Foundry Networks....09/27/99....525% ...
I did a little more research and came across similar "bubble talk" article about Google, from 2004 (Technically there was a bubble, just wasn't tech induced).

Is it possible we are shell shocked from the last one and even minor excitement makes us all scream bubble in unison?
