I've never written a line of publicly accessible code in my life, I've been working for 20+ years and I rarely fail at getting an offer for a job I apply for. Then again, I don't submit resumes blindly. I always go through recruiters, that has more to do with my hit rate than my skill set.

Let me take that back. I got my first development job in college from another school about 100 miles away because he saw a HyperCard Eliza clone I wrote and posted on AOL back in 1993.
