We always are trying to help the ColdFusion community as much as we can. We had a CFC best practices document in our ColdBox documentation site in order to steer developers in the right direction when building components. I have updated the document to now include more topics than just CFCs. So if you are interested in collaborating to this document or think some points are useless, please comment and we can make this document better.
So here are our ColdFusion Development Best Practices document: http://ortus.svnrepository.com/coldbox/trac.cgi/wiki/cbDevelopmentBestPractices
