No the craigslist RSS links seem to work. Just they seem to be blacklisting newsblur (again). This happened last year too see: Problem with Craigslist and Ebay feeds
If we all submit polite requests to craigslist they will likely un-blacklist newsblur again. But it took almost a month to get it back last summer. You can do it from here https://sfbay.craigslist.org/contact?step=form&reqType=suggestions
