Ryan MacCarthy writes "When Google and Yahoo! released their map APIs last week they unleashed a horde of hungry developers eager to integrate their data with the user-friendly maps. Brilliant hacks like Chicago Crime and Craigslist Real Estate are in the midst of switching over to the new API, while sites like MetroFreeFi use the new API to make it easier to find free wi-fi locations in US cities (San Francisco, for example). Imaginative developers, like Alan Taylor (Transparency concept), are digging deep into experimentation to dream up new uses for the maps. It's great to see the innovation when hacks turn to apps." I want to see Los Angeles maps of the action in James Ellroy's novels, and a national map of the worst, funniest tourist traps across the U.S.
