just a thought

Google search or all google services?

If just search:
1. Not be immediately affected
2. Be sad that they fucked up this bad and ruined their reputation
3. Watch their share value crumble

This isn't totally unprecedented. In July 2004, the mydoom worm shut down Google for a couple of hours. This shutdown was right on the verge of their IPO, and we saw the effect it had on the price (none!) :)
