"Meta Search Engine" means that FreeMedMatrix compiles results from several search engines and services. For example, a Google search provides only web pages available in the Google index.
Google Powerpoint Lectures
AAFP Patient Ed Handouts
Family Practice Notebook
National Practice Guidelines
Dermis Skin Disease Images
Medical meta search is not a bad idea but the interface looks cluttered.
The webmaster of FreeMedMatrix sent an email announcement about the new service to a few medical bloggers yesterday but I did not really pay much attention to it until I saw the link on KidneyNotes.com. Having the email address listed on the blog page has the adverse effect of receiving 70-150 spam emails daily. Gmail generally does a good job forwarding them to the spam folder.
