hCard-GoogleMaps-Mashup
Microformats gain momentum, slowly (maybe more slowly than expected) but steadily. Now Christian Heilmann created a mashup of hCard and Google Maps aptly called hcard2gmap. The javascript parses a web page for hCards with geo information and relays these data to Google Maps where the contacts are being displayed by markers. Great stuff, more applications like this, please! Check out the demo here.
