After speaking with Shekhar, it's clear that the storm has secretly been a blessing in disguise. Team Topomancy will be done with the Gazetteer database by Wednesday, giving us the possibility of two days to actually build an application on top of it.
While we've been talking a lot about Ghostmap; I'm not sure this current incarnation is directly germane to the gazetteer.
One thing that might work really well could be the Fast Food Locations tool we had prototyped a few months back. In that case we'd be authoring new gazeetter entries and gives the gazetteer something of a corpus to operate on.
Any other ideas as to what we could spend those 2 days building considering we'll be able to dedicate the full force of everyone to the project?
