Show HN: healthysparx.com - A social Q&A site for health topics

I'd appreciate any feedback, thoughts or comments on our website - healthysparx.com

Being interested in living a healthy life, my wife and I were discussing that were no modern health sites that really leveraged the power of Web 2.0 and the culture of social networking to help people live become health aware. So we decided to make our own.

Our website currently does the following things:

* A personalized news feed

* Catalog questions according to topics

* Comments on questions/answers

* Following other users and topics on healthysparx.com

* Users have basic profiles

* can sign up using Facebook or Twitter and search

Looking forward to seeing your feedback.
