I love maps! One of my favorite TV shows was/is “Mit offenen Karten” (Le dessous des cartes) of the German/French TV broadcaster ARTE that explains the world with maps. Also the map of online communities made by XKCD simply fascinated me. Especially when you compare the Updated version of 2010 with the 2007 version and realize that Myspace.com almost disappeared. But in terms of roleplaying and especially Earthdawn the Atlas of Barsaive made by Telarus is one of the best you can find.
But today my attention was caught immediately when I read at Inkwell Ideas about an Hex map of the RPG community. The interactive map of the RPG community was made by Morro from ENWorld, he used the Hexographer of Inkwell to display the RPG communities based on member figures (One Hex = 1000 members). I say GREAT STUFF!!
Have a look at the INTERACTIVE HEX MAP OF THE RPG COMMUNTIES
Unfortunately the RedBrick forum has not enough members (542 atm) to fill one Hex. Not one Hex!!! Conclusion: Play more Earthdawn!!
