Welcome to Code Review Stack Exchange

Code Review is a question and answer site for sharing code from projects you are working on for peer review.
It's built and run by you as part of the Stack Exchange network of Q&A sites.
With your help, we're working together to build a library of detailed code reviews.
That wording has been in place since January 2013, and it just echoes the standard formulaic greeting used on most other Stack Exchange sites.
I don't think that the wording suits us. How should be better summarize our mission to newcomers?
As examples of sites that deviate from the standard template, see Ask Patents and Ask Ubuntu.
