Some user voting might be nice.  This would likely create a canonical cheat sheet for each section.<p>For instance, here <a href="http://devcheatsheet.com/tag/ruby/" rel="nofollow">http://devcheatsheet.com/tag/ruby/</a> the first cheat sheet isn't even ruby specific, and I think this is a lose.<p>Otherwise, a great site I'll likely be using it in the future.
