Do you mention it in your resume or cover letter? We try to look up information about people (blogs, open source contributions, etc.) before or between interview rounds, but it depends on how much the candidate pushes it and how much time the interviewer has to look into it. Just having committed to an open source project would put you way ahead of most of the people we interview.
