> every attempt at answering a question - is valid and should remain.

Yeah this is describing a policy that seems like it’s causing some of the problem I’m talking about. SO’s current state today is evidence that not every attempt at answering a question should ‘remain’. But of course it depends on what exactly we mean by that too. Over time, valid attempts that don’t help should arguably be removed from the default view, especially when high quality answers are there, but they don’t have to be deleted and they can be shown to some users. One of the things it sounds like SO didn’t identify or figure out is how to separate the idea of an answer being valid from the idea the answer should remain visible. It would serve the site well to work on making people who try to answer feel validated, while at the same time not necessarily showing every word of it to every user, right?

That would entail a significant redesign of the underlying display engine... and an agreement of that being the correct direction at the corporate level.

Unfortunately, after Jeff left I don't think there was that much upper management level support for "quality before quantity" After the sale it feels like it was "quantity and engagement will follow" and then "engagement through any means". Deleting and hiding questions or answers that aren't high quality... really would mean making most of the site hidden and that wouldn't help engagement at all.
