If you like that, then you might want to add the following feeds to your friends list:
- imaginaryatlas, which posts such things as a topographical map of Skyrim;
- fy_cartography, which is mostly a constant stream of maps and photos of places with maps;
- mappingworlds, which is the weblog of Clercon, a Swede who is one of the top map makers with Profantasy's Campaign Cartographer; and
- rpgmaps, which is the weblog of the aforementioned Campaign Cartographer. They do a monthly digest of the maps posted in the forums.
There is also The Cartographer's Guild, where a lot of people congregate to show off the maps they made. Most use Photoshop or Gimp, and the tutorials are really interesting.
