James Fee (of Spatially Adjusted fame) has launched his newest project: A GIS blog aggregator called planetgeospatial. I’ve just subscribed to its RSS feed, which has the great feature of linking you straight through to the blog of the article you’re reading (rather than to planet geospatial). I like it, as it helps prevent interesting stories falling through the gaps.
While your at it, if you’re coming to Google Earth from the GIS angle, then you might also want to consider looking at Planet GIS, another aggregator (that alas does not sport an RSS feed), and SlashGISRS, a Slashdot-like site for GIS matters.
