Craigslist, crgslst, and Crawlers

The Read Write Web has a good post about crgslst, a new search service for Craigslist:

Denver, Colorado based Superhero.es has built crgslst, a very slick multi-city search tool for Craigslist. Craigslist itself doesn’t offer a multi-search service. By combining the publicly available RSS feeds from Craigslist with AJAX, crgslst fills this need “so fast, we left the vowels behind.”

Unfortunately, crgslst may be in violation of the Craigslist terms of use and could face the same shutdown that other similar projects have in the past. This situation brings up a number of questions about intellectual property, RSS and mashups.

I still find it amazingly odd that Craigslist blocks 3rd party crawlers, especially of their RSS feeds.

Craig has gone out of his way to point out that Craigslist is a being of light which doesn’t pursue the all mighty dollar to the detriment of community service.

So why are they not letting the community use their service by building cool apps on top of the data?
