German blogger geoberg.de has compiled a list of 101 geoblogs. I'm reposting them here to help spread the word. There are a lot of talented people sharing fascinating and well-written ideas and news out there. The role of geoblogging is still in its formative stage. It's exciting to see how quickly it's growing and diversifying. Thanks to Callan Bentley at NOVA Geoblog for spotting this list.
