I don't get to spend too much time on Sermo because I'm so busy blogging. However, ever since I added the link to Sermo on my blogs, I've referred over a couple hundred of physicians! You can see how many physicians you referred by logging into your Sermo account and clicking on the "My Account" tab. Then, you can click on the "My Referrals" link on the lower left side of the screen and see how many physicians you've successfully referred to Sermo .
If you're a physician and you haven't joined Sermo yet, what are you waiting for?
