BusinessWeek - Mix, Match, And Mutate:
"Looking for a place to live last year, Paul Rademacher pored over Silicon Valley rentals on craigslist, the popular online classified-ad site. But the 3D-software engineer grew frustrated that he couldn't see the properties' locations on one map. So Rademacher hacked his own solution -- a Web site that combines craigslist rentals with search engine Google Inc.'s (GOOG ) map service. The listings on HousingMaps.com appear as virtual pushpins on maps of nearly three-dozen regions around the country. Click on one, and up pop the details. Since its public debut in April, the free site has drawn well over a half-million unique visitors."
