Well, I haven’t actually done anything but I’ve been pondering!
I think a neat tool website feature(?), would be dead-simple to use WordPress plugin that allows users to place themselves on a map and can be installed here on Ludumdare for future competitions. I did this by hand a long time ago but it’s time to enter the 90′s or whatever.
After some initial looking around I can’t find anything existing that really fits the bill.. a requirement would be the end result has to show the names directly on the map, not just those dumb balloon things. It looks like this can be done with Google maps using elables. Hmm, would be nice if they were clickable to bring up more info as well…
Also, it should be smart enough to only show people on the map who have made at least one post in the active competition so the map stays more or less readable totally zoomed out, at least for that mode.
