Enough of our economy is tied to the internet now (and in the future will likely be more so) that it is becoming possible to actively effect stock markets through interrupting key areas. If you can DOS enough services Amazon, Google, Yahoo, MSN, ebay, etc. for long enough you will get a significant response. Especially denying access to search engines would full-out cripple most peoples internet usage. I'm guilty of the crime of using google search to find URL's that I know off by heart and I'm a techy. The vast majority of people don't remember URL's (besides perhaps google and facebook) that they'd never survive a search engine block out. It would be difficult to DOS Yahoo, Google and MSN simultaneously. However, it's not impossible. Hack enough DNS servers too and you can DOS anything.
