Good idea. I've been part of a development team working on a similar space. Instead of medical conditions and topics, it was research progress in specific areas - feeds on most recent articles, cutting edge results, methods and procedures that have seen results. I think we are going to be seeing a lot more this in the near future.
Thanks! This idea came out of the fact that we built an enterprise Radian6-like platform specifically for the health vertical and realized this would be a useful tool for consumers as well.
That and people send so much time searching for this stuff anyways, we might as well help them out.
