“being humble” is not the same as saying one should be an utter doormat: there’s nothing wrong with self-confidence. Just don’t come off like a know-it-all. Even better, think about going for a “collective” ego instead; rather than worrying about whether you’re personally awesome, try to build a sense of team accomplishment and group pride. For example, the Apache Software Foundation has a long history of creating communities around software projects; these communities have incredibly strong identities and reject people who are more concerned about self-promotion.
