Matt Taibbi from Rolling Stones reports:
Ostensibly, the law makes it easier for startup companies (particularly tech companies, whose lobbyists were a driving force behind passage of this law) attract capital by, among other things, exempting them from independent accounting requirements for up to five years after they first begin selling shares in the stock market.
Is just wrong. You still need audited financials to be a public company (current, plus 2 years prior to IPO instead of 3). I believe what changed is some of the Sarbox rules related to rotating auditors, etc. See http://www.orrick.com/fileupload/4624.htm for one leading law firm's analysis of the JOBS act.

There is certainly room to relax some of the regulations put on small public co's by Sarbox. That's part of the reason companies are listing on foreign exchanges, and let's be honest, you dont' see "fraud running amuck" on the London Stock Exchange do you?
I like 37 Signals approach to building products and many of their business philosophies but they seem to have a need to relentlessly attack any other way of creating a company or doing business. Not quite sure why.
