Totally concur; I've been giving myself a crash course in GIS as I ship for a house. Seems like a lot of GIS tools, although very flexible, are not built to handle a city's worth of fine-grained data. PostGIS is the only one who loves me!

I'm curious what a (consumer-level) house seeker can do with PostGIS that existing services can't provide. Do you merge and use datasets, etc. I was thinking of doing this in my own house search, and I would be happy to hear some pointers...
