The Crib Sheet has moved to a permanent home. I threw it into this site’s template for now, but I may choose to do something differently, eventually. Perhaps a PDF or two. The good news is that my print style sheet should allow for a relatively clean printed version for now.
I’m referring the Sheet to this post, and leaving it open for comments indefinitely. Feel free to add more suggestions below. Remember the focus: practical, real-world tips that aren’t picked up in the spec, or by the validator. Things that are easy to trip over, and may not make sense without external knowledge.
