I think it again depends on what you mean by hacker. If a web developer is passionate about web development, learns everything he can about it, enjoys doing it, and approaches it like an aesthete, then according to the author he is a webdev hacker (or whatever you want to call it). There are many other definitions of "hacker" that wouldn't include the aforementioned web developer (I'm thinking of Eric Raymond's essay on the topic). In the end, there doesn't seem to be a broad agreement on the topic.

I find this quote from the article very relevant (and I agree with it):

Equally important, though, is the hacker's attitude. Computer programming must be a hobby, something done for fun, not out of a sense of duty or for the money. (It's okay to make money, but that can't be the reason for hacking.)
