Who is the target audience for this sort of advice?

The people who will understand this figured it out long before they were in a position to hire other people. It's just obvious and is repeated so much (don't hire for specific experience) that it is a cliche.

The people who don't get this will never get it, even if you paste stickers that say it on the windshield of their car and whisper it in their ear as they fall asleep each night.

So it's all great to repeat this for the 3 newbs who joined our community in the last 5 minutes and haven't heard this 80 times already this week, but it shouldn't be on HN's homepage.
