I was reading the Stack Overflow blog earlier today regarding the greatest hits of the Stack Exchange sites.
I realize that these posts are what make our site popular across the Internetz and hence, I think we should work to make them even better.
I feel that things like adding screenshots where necessary, editing the titles and body for a clearer answer and retagging appropriately such that the questions even more discoverable can be done to improve the quality of the site.
(On a side note, I have edited a couple of my answers that were featured in the greatest hits to make it slightly better than before. I would love some feedback on that.)
