Sadly as HN has become more popular it really ought to be renamed Larval Stage Hacker News. Recently some pretty bad articles have made the front page, like The 5-minute Guide to C Pointers which embarrassingly conflates arrays and pointers, or my personal pet peeve, the endless stream of puffy $EDITOR advocacy posts, for those folks who are still on the fence about what tool they're going to use to edit a fucking file.
Anyway, as much as I complain about all the puff pieces, there are still plenty of articles with real technical meat on HN, you just got to wade through some crap to get to them.
Actually, a lot of us come for the articles but stay for the conversation. That pointer article may have had an error, but it was discussed in the comments.
That's the hacker ethos - show what you know, if you are wrong someone will point it out and others (and hopefully youtself!) will learn from it.
The sort of attitude you are display is the sort of hypercritical one that prevents people from submitting "Show HN", which is a real pity.
