Garett Rogers at ZDnet is previewing the preview of Google Health, a new enhanced way of searching for medical information.

“Lots of people were hoping for a more feature-rich product (including myself) but that’s not usually how Google operates. They like to see and hear what people want before they spend time developing what they think people want — this is how they get things done so quickly.”

That is an interesting point. Pare down everything to its essentials, then let users’ comments and requests build the service over time. There’s no doubt the Googlers know all about Web 2.0 and the way to squeeze out services like toothpaste from a tube.

“Google Health delivers better results to users searching for medical information without them having to learn how a new service works. I do hope they eventually expand this service so it acts more like a health information portal.”

Doesn’t it have similarities with Google Finance? “I’m thinking it could turn into a service like Google Finance that links a bunch of Google services together.”

To try out the service, go to http://64.233.167.99, a Google datacenter, and search for anything medical.

We will watch this useful idea as it develops.
