Clicking on the link, I believe they mean "use Craigslist to apply for a job elsewhere". It's hard to believe anyone would bag on Craigslist itself as a model of efficiency; If you were to chart number of uniques per day against number of employees, I doubt anyone is within an order of magnitude (or two, or three) of Craigslist.
Wikipedia.
Oh, good call. Thanks.
The link was to the SF craigslist jobs page. I think they meant go on Craigslist and apply for another job there, rather than work for the Craigslist outfit itself.
If so, it's a pretty internet-noob way of stating it.
