When I first looked at OpenStreetMap a couple years ago I dismissed it solely because I didn't like the tile design. But now I see more and more really beautiful designs popping up (e.g. also those from http://mapbox.com/) and I expect OSM to gain a lot of importance in the next years (overtaking Google Maps maybe?). These 3rd-party tile designs a beautiful example of how much more can be done with data that's truly open!
The one thing I don't understand is who pays for hosting it. Once everyone uses OSM, won't it be prohibitively expensive for a non-profit to serve it? Maybe I'm wrong and it's not that much of an issue. Does anyone have an idea how much it costs Google to serve the Google Maps API? Wikipedia is in the same situation, and they solve it with their donation pleas. Maybe it would make sense if a fraction of our ISP bill automatically goes to the most visited non-profit websites. They offer kind of a public good to everyone, after all.
