CraigsList derived an estimated 53% of their revenue from job listings, 30% from adult ads
Not surprising, as those are markets with a supply-demand imbalance. These seem to gravitate towards marketplaces that require lots of hoop jumping, I guess because it artificially pares down the demand.
It does not look like number of job postings on CraigsList grew much.
Number of job postings overall on all web sites in the last grew more than on CraigsList (due to recovering economy).
The adult ads went out the window which is going to hurt them, a LOT, in terms of both traffic and revenue.
So the more material question is has CL's largest revenue category - job's - been disrupted?
I was able to dig up this graph of job mention volume and it appears that CL, in their most important category, is gaining velocity, not slowing down:
