<p>As a newbie I think it might be informative that I share my experience. Cross-validated is intimidating, period. There are a few reasons for that, some of which are preventable, some of which are not (perhaps this idea deserves its own meta discussion). Anyways, apologizing is a natural response to asking others for help, particularly because you may feel like a burden. I understand it is important to let people know that they are not a burden: just be careful not to tell people that they "don't" need to or "shouldn't" feel bad; instead just let them know you're glad to help. </p>
