I first noticed "online geospatial media" in the 1990s. I was working at Esri and I was loyal reader of Directions Magazine. Later I started my own newsletter, GIS Monitor, and briefly edited EOM. For the last ten years I served as as Directions' Executive Editor.It was just about ten years ago that online geospatial media offerings exploded. Blogs were the new hot thing back then and to celebrate I wrote A Reader’s Guide to Geoblogs. I was a big fan of Planet Geospatial, James Fee's automated geospatial blog aggregation site and gave him a made-up award: the Directions Media Special Achievement in Blogging Award for 2006.
Fee shut that site down last year. And, last week I learned SlashGeo, a human-curated aggregation site shut down. Another effort to consolidate geospatial in one place, GISBuzz, seems to be gone, too. I saw on Twitter that it was "for sale" as recently as May 24. Now the domain is parked.
