This is something I struggle with as well, but I think it's your response that matters more than the feelings of inadequacy you might have when comparing yourself to the very best parts of any community.
Does your perceived lack of talent drive you to learn and become better? Are you actively looking for opportunities and inspiration to drive you forward? Or are you simply idling on a web page re-living other people's accomplishments?
It's a thin, dangerous line. Some people idle, some people drive forward. I wouldn't suggest that either is the 'right' thing to do (I think it's morally ambiguous) but my desire is to drive.
