While I agree it seems the above comment was intended as a swing at HN which is not constructive or useful debate, I would suggest that as per the stack overflow developer survey web programmer was the most common job title by a very large margin (72.6%, with next closest being Desktop applications developer at 28.9%)

While I would suggest that this forum demographic likely differs somewhat from stack overflow as a whole, its certainly an interesting question.

Also as an anecdote, web technologies stories seem to appear disproportionately often on the front page. This would suggest at least some interest by the majority of HN
