Being part of the community and just asking questions is no big deal in my opinion. Helping others with soft- and hardware-related problems and developing bug fixes for open-source software is what I mean. Ubuntu is built on the open-source community after all...
Contributing to it feels like a duty to me; maybe because I love this OS so much
