As a primarily puzzle-as-challenge site, we face some unique challenges working in the SE framework because of the ways our site's philosophy differs from usual. Many things are the same, but the differences are likely to be where we find gaps in the features of SE for our purposes.
I think it would be a useful exercise to write down these differences and note some of their consequences and how we can best make them work. This is meant to focus on challenge questions; questions about puzzles are much like in other SE's.
Please post one difference per answer.
