(1) My experience is that commercial and government GIS map data is less
than perfect; particularly if you're crossing international borders.
Even if you're targeting North America, it turns out the whole
architecture of commercial information (generally built on top of the
national census) is entirely different in Mexico, Canada and the US.
Project #2 in the pipeline is a fundamentally international GIS system
that wouldn't be possible at all w/o dbpedia, geonames, freebase,
Yahoo's shapes, and Open Street Maps; unless I had the kind of
resources that Google has.
(2) A big part of the Web 2 -> Web 3 transition is going to be finding a
way to clean up the tagging morass. When it comes down to it, tags
suck for two reasons: (i) they're a lot of work to create, and (ii)
people don't use them consistently. There's are many approaches, but
it's one of the biggest problems that I see in front of me personally.
