Skilled programmer has the proficiency and courage to attack the problem and win. There's some boldness coming from knowledge and experience, and i like people showing that. On the other hand an unskilled person will not be able to understand the design, will be afraid to make changes, will get confused and ignore the parts they cant understand, and will not take the responsibility and initiative - they need to be guided all the time. Then i dont care if they're humble or not, there's nothing to be gained.
