This is a really interesting baby "attack" that brings a bunch of important stuff to the fore. Imagine when 10x more people know about SN, what then?

There are a handful of really innovative things going on in SN. One of them is the imposition of real costs and incentives. If someone posts garbage, and others are posting non-garbage, the most obvious way to demote one and promote the other is by imposing a feelable cost on posting, and by users zapping valuable stuff.

I feel like users are generally quite lazy in their zapping -- aside from a small number of things that get a lot of engagement, there's a massive amount of stuff that gets nothing. Which means that, in the eyes of the system, a huge amount of stuff is equivalent. But I don't think it's really equivalent.

Perhaps the first step is for useful things to differentiate more through zapping; which is a user issue.
