Not sure what you're doing, but you might want to check out the Flickr shapefiles that they CC0'd a while back < http://code.flickr.com/blog/2009/05/21/flickr-shapefiles-public-dataset-10/>. They were generated by looking at the lat/long of uploaded photos along with the user input place name for each photo, so they're not terribly accurate. There's a lot of "blurring" around the edges of cities, for example. But maybe they'll work for you!
If the Flickr shapefiles aren't accurate enough for you, and you have a list of cities you want shapefiles for, you may be able to pull that data from the Yahoo! GeoPlanet API (assuming their ToS isn't a problem). Mike On Wed, Jan 13, 2010 at 6:00 PM, William J.
