This article is pretty off. This is not the "feature" of PadMapper. PadMapper made it easy to locate aggregate postings on Craigslist, along with the ability to filter those postings by attributes. Additionally, they provide some auxiliary information, such as pricing vs median pricing, WalkScore, etc. Craigslist just added an embedded map on the page - something that wasn't already too far away with a click to "google map".

More of the same sensationalist journalism.
