I think the problem is that we've trusted people over time to do opens on their own but there's been a strong tendency not to and without opens, new people have trouble hooking in. Without fresh blood, the game won't make it.

I'm leaning most in my personal preference towards the open post or two threads option though. At least that way if they don't put up an open, it means players would be tagging someone else. The combo might lead to some doing opens and others meeting their AC by tagging around.
