GeoURL has been revived - or rather, a new GeoURL service has been built. Simply go there, register your own site, and then integrate a link like my nearby link. And suddenly we can see who's in the vicinity again. The whole thing is still somewhat spartan, but it's enough to find neighbors (greetings over to Paderborn and groetjes naar Enschede!).
By the way, to help my rusty Dutch (I can read it relatively fluently, but write it only extremely haltingly), the German-Dutch dictionary at pauker.at was helpful.
Update: cool, no sooner do you post about it than other neighbors resurface. And what do I discover: Gedankenschnipsel is now also running on WordPress.
