There was a link to here on /r/programming. What really got me hooked wasn't all of the articles about startups, etc., but an interesting Wikipedia article. I forget what it was, but it was in the same vein as "White Coke" on the front page now. In the comments of posts like that it's evident that some people think they don't belong on HN, but to me they are reminders that there is really cool and interesting stuff out there that I have no idea even exists. At least getting rid of them would keep the kids out, or it would have me.
