I love a good cheat sheet; anything to condense a big ol' reference site into a page or so that I can flip to when I need it.  However, no one has made a good cheat sheet (or even a good reference, period) for the new RESTful Rails stuff.  The best one-post reference I've found is simply_restful in Rails Core on David Goodlad's blog.  Plenty of bloggers rah-rahed about simply_restful and gave a few examples of how to set it up, but David includes something unique: a table of all the auto-generated named routes and how to use them.  I swear, I must have spent half an hour looking for exactly that information.  Ah, sweet spoonfeeding!  Thanks again to Mr. Goodlad for putting that out there.
