Flagr

This Flagr mashup (you can tell that's what it is because it's got that r-without-the-e naming thing, which is getting old, people!) is a pretty nifty use of Google maps and social networking. Tag interesting locations (with pics if you want), restaurants, bars, ski resorts, etc, and push-pin them on a map. It just launched today and pins are popping up already.

And 'sharewhere' is a clever subtitle (supertitle? go see their logo, you'll see what I mean)
