The amount of negativity in this thread is depressing. I think a lot of people either didn't read the article or just skimmed it. For those of you who are citing Peter Norvig's essay, I also thought of the essay when I read this; it's one of my favorites. I've read it several times because it is humbling and inspires me to rise to the challenge of really becoming a great programmer. If Matt reads it he might feel similarly (if he hasn't already).
But do you really think Norvig would suggest that someone at his level is not a programmer? By my count, he's done about half the things on Norvig's list already and could be within a tenth of the fabled 10,000 hours (12 wks * 7 days * 8-16 hrs = just over 1000 hrs).
I agree that the title might have been misleading given how much prior experience he had, but seriously, this is one of those "if you don't have anything nice to say" moments. If he received that many emails from some random comment on HN that means there are a lot of people reading this thread right now who are in the same boat as he was and as the people asking for help are. What kind of community are we (I mean we as programmers and we as HN) if we denigrate Matt's efforts and these kinds of blogposts?
There are going to be more and more programmers in the world as the pace of computing accelerates and people are exposed to gadgets and technologies that excite them enough to peek under the hood. We should be encouraging them and welcoming them and telling them "yes, programming is awesome!"
