To move one step further in the direction you indicate, I think wiki should summarize the topics of the articles, not the articles themselves. This is also how it's always been. So a thing to do with good articles (estimated by how useful it would be to recall their content in later discussions) is to make sure their useful content is summarized in appropriate wiki pages, and to link to the articles in their "Blog posts" sections.
(I'm not sure what adamzerner meant by linking to that quota page, so I'm not sure we are discussing the same question.)
I think it'd be a good idea to keep a list of the ways we'd like to see LessWrong improve, sorted by popularity. Ie. email alerts for new responses.
So if you have an idea for how LessWrong could be better, post it in the comments. As people up/downvote, we'll get a sense for what the consensus opinions are.
I think there's a pretty good amount to be gained by improving LessWrong.
Note: I say "ways to improve" instead of "features" because "ways to improve" is more general.
