Do we want code or design reviews on this site?

Code reviews expect considerable effort on the part of readers, more than a typical question. Furthermore, they are very open-ended — “I can't see anything wrong with this code” is a valid, but not that interesting answer (and what about “I can't see anything wrong either”, which is a *different* answer for every “I”?). Design reviews require less reading effort, but suffer from the same problem with answers.

This has been discussed about [Stack Overflow](http://stackoverflow.com/) before. The discussions I could find are:

 * [Is Stack Overflow an appropriate place for simple code reviews?](https://meta.stackexchange.com/questions/28540/is-stack-overflow-an-appropriate-place-for-simple-code-reviews)
 * [Should SO allow "give me some feedback" questions?](https://meta.stackexchange.com/questions/1957/should-so-allow-give-me-some-feedback-questions)
 * [Where can I post code for others to review?](https://meta.stackexchange.com/questions/90362/where-can-i-post-code-for-others-to-review)

There is now a [Code Review Stack Exchange site](http://codereview.stackexchange.com/), but this should not influence our stance of what's acceptable on *this* site too much.

This meta question was triggered by [What else could I lock down for buildbot runs?](https://unix.stackexchange.com/questions/18683/what-else-could-i-lock-down-for-buildbot-runs).
