Frappr (friend mapper) is more like place mapper (plappr) or event mapper (eppr) or experience mapper (exper-appr), this Web 2.0-informed mash-up service featuring Google Maps and inspired value-add by what looks like the folks who did "Hot or Not" long ago (they've continued that legacy of drop-dead easy UI to vote / map / contribute here) as lots of possibilities.
Put your pin in the map: name, zip code, shout-out (contribution, post, comment). It's that easy to add knowledge and experience, time and location ID's, and put into a very usable UI, both visually with all Google Map functions like Map, Satellite, Hybrid and I thought I saw RSS buttons around, indicating that new additions to the map would be available blog-like ready for reading in My RSS Reader / Yahoo / AOL / MSN, etc.
