I’ve pinged MetaCarta before, when they got more than $6 million from Sevin Rosen, but Shore points me to a good overview of MetaCarta’s technology in Directions magazine. Geo-located content/search has been something of a blind spot for me, reading through this helped a lot. Seems MetaCarta does something akin to WebFountain, but only for location-specific information. Geolocation unlocks all sorts of interesting applications, in fact, the concept came up several times in my conversations with Bill Joy this past Friday. Watch this space.
