HN is effective because it's so narrowly focused. Yes, there are submissions that deviate somewhat, but because of the initial focus, the outliers remain (for the most part) intelligent and interesting. If you broaden the focus, you also broaden the range of the outliers, and we'll start getting completely unrelated posts.
So do I, but there are always going to be posts that don't "belong". I'm just saying that at least the way things are, at least the outliers are Web 2.0 news. But we should under no circumstances change the mission of the site to better match what's being posted. If we expanded the intended focus to include those, HN will end up looking like valleywag.
