Marissa Mayer, head of search at Google, did indeed show up at the Web 2.0 Summit conference in San Francisco today, albeit briefly. Mayer presented what Summit organizers call a "High Order Bit" -- a 10-minute glimpse under the hood at what's going on with medical-related ventures in the Googleplex.

Well, not exactly "under the hood." Mayer talked about Google Health, an emerging division for the search company. You can stay tuned on InformationWeek for a news story about Google Health.

10. "People with your problems also searched for …" 9. Google could start a series of health-related Orkut mashups, like Rashbook, Boilbook, and Wartbook. 8.

Then Google could sell you Rogaine. 5. Google paternity search. 4. Typing in symptoms returns "Did you mean estate planning?" 3. An "I'm feeling yucky" button. 2. Viagra spam will now be sent only to those Gmail users who truly need it. 1. Your Google calendar mysteriously ends on April 21, 2044.
