Now I know people talk about impostor syndrome whenever they mention the woeful lack of diversity at tech conferences. Interestingly, I felt like an impostor at FOSDEM - not because I'm a woman (there were quite a few techy women around at FOSDEM, more than I expected) but because I'm not an open source person.
