I'm not chalking this one up as a win. This is Craigslist doing the bare minimum, just like they did when they developed mobile/tablet versions of the site. They build half-features that ultimately aren't that useful, but are enough to quell the angry masses. And given that embedding a map should be fairly simple, I'm surprised that they're having trouble with it:
