One nice feature of the posts is the ability to "recommend" them. We have set 5 recommendations as the minimum to get a post on the front page. So far, no one is recommending anything, even King of the Hardwood, and I suspect it's because it's not obvious how to do it.
At the end of the post and before the comments click on the green "recommend." You can always "unrecommend" if you click by mistake.
