Practice Fusion is a startup making waves in the health 2.0 market. The product is a free, web-based EMR (electronic medical record) system for physicians. It runs in the browser and has been marketed as a 'Google Apps for doctors', providing patient management, scheduling, secure email and more.

The business model is largely serving ads, which allows the product to be free - although users can pay $250 $100 per month for an ad-free version. The company has just announced it has signed up 1,300 medical professionals since launch in November of 2007 and is currently serving "more than a quarter million patients."
