Craiglook.com is a useful RSS mashup for Craigslist. Here are some features that help craiglook to make big difference when it comes to searching/browsing craigslist1. Search radius
Say, I'm an average Joe looking for a car. With craigslist, I go to "newjersey.craigslist.org", then "southjersey.craigslist.org" then "centraljersey.craigslist.org", then to "newyork.craigslist.org", then to "philadelphia.craigslist.org" and to 10 other adjacent craigslist locations to find what I need.
With Craiglook.com all I have to do is to set my location (e.g. Pennsauken, NJ) and define what's my preferred range is, (0, 10, 50, 200 miles or even nationwide) and press the "search" button (yes, I don't mind traveling even 100 miles to get a great car deal). 2. No spam
Craiglook cuts through crappy postings and spam in realtime, keeping only posts which are more likely to be local results (who cares about "nationwide blowout car sales" if I'm looking to deal locally ?) 3. Usability
Picture Previews, brief description, phone number and poster's email – Do I have to explain why it's all a must for a decent classfieds website ?
