Awesome! and glad someone is putting some effort into the map feature.
While you are at it, a few suggestions that pertain to the larger mapping and not just for locations.
#1
Would be AWESOME if when looking at the player map if the icon was differnet for those with active FS posts. Maybe another color for active wislist game or 2. I can explain the 'why'. When looking to purchase a new game, distance is oftena huge factor. If the market feaute could be combined with the map feature then I could mor easily search a radius. Same thing with selling a game. If I could look in the immediate area to see whom is looking for a game then I would reach out to them directly.

Thing this is a bug with maps. If I click on a the location under someones avatar (for example Seattle on laughingotter) it just goes to the big zoomed out world map
