What is NavMarker, you ask?
NavMarker is what's around you, that you might not have known.
Not just any spot though. It's the offbeat. The awesome. The geeky. The newsworthy.
NavMarker changes daily.
Everybody can add markers, and every marker has an expiration.
You control the expiration dates.
Hype Up the markers you like, Lame Down the ones you don't. Voting changes the expiration. The best Markers can stick around forever, and the worst could disappear in a flash.
