re: ("What lesson did you learn in the last year?") Craig: How foolish I can be, in general.
foolish about what? craigslist did slip up in ranking but that doesn't seem to have been the result of anything Craig has done... (very likely the result of going on NOT doing things, like NOT using profits to get customer service and improvements at some sort of a decent level)...
... or was there something personal he regrets having done or not done...?
P.S. vague and ambiguous as always... D.
