I think the poster's point was that "Ask HN" posts are becoming less common (either posted less frequently, or just aren't voted up to the front page as often as they used to be).

I'll admit that I miss this a lot too, to the point where I often just go through and upvote all except the most trival "Ask HN" posts. The ability to ask for good advice from a very smart group of people was once one of the best features of this site.
