Today I met a friend who is also using Stack Overflow. He had a job interview today at a small business and during the interview, the prospective boss asked him how he assures that he's alawys up-to-date concerning technical questions and what he's doing to seek for a solution for a problem he can't solve by its own. Besides some magazines, journals, books and blogs my friend also mentioned Stack Overflow.
The prospective boss seems very interested about that and asked him if he could tell him his username. It appears that was the most difficult during the whole interview ;) Would you tell your prospective boss your username? An the pro side one can mention that the boss sees that you're very involved in your business and community but on the other hand it is a really private thing and you can't post anymore in thread like "what was the worst working environment?"
My friend circumnaviagted this question by a rather lame answer (more or less: I use autologin, that's why I have to check the username later at home, I'll maybe send you an email.)
