Tag Cloud for MedlibBLOG and Consumer Health Search engine?

With the really cool Medlibblog search and the Consumer Health and Patient Education search engines we have two very nice options to search, but I wonder if it is possible to produce somehow:

• a Tag Cloud of these CSE resources or even get
• an RSS-feed on all that is new?

Instead of searching we could browse and see what's new & hot. Who knows how to tackle this the best way? My first guess would be:

• collect all RSS-feeds of included resources and insert them in a new blog/site. We already have these feeds on the wiki about Medical Librarians blogging.
• ?
