Stack Overflow got a mention in the Guardian's Ask Jack column for 2nd July.
NOTE: I'm still not sure of the etiquette for this sort of thing here on MSO. I know it would get closed straight away over on SO, but I'm hoping we can be a bit more flexible here.
UPDATE: The other links are interesting, but I was thinking about primarily non-programming related media. I get the impression that the sort of people who write into "Ask Jack" aren't particularly computer or Internet savvy so they aren't likely to come across Stack Overflow directly or via the blogs etc. mentioned by others.
