[Commentor] LC-293 Ian Jacobs [Working Group decision] Generally speaking, we think the imperative voice better convey our message across. For the specific best practice on short URIs, we have added a explanatory words and examples, but have kept the best practice mostly as is. [Commentor reply] yes [Comment] 
I realize that you have chosen to write the good practice notes in the imperative voice. I also realize that more information is provided below. However, I think the reader might take away a lot more if the points included more rationale. Any many people (including myself initially) may simply look at the checklist and not take time to read the entire document. For instance: "Short URIs require less effort to type, are less prone to errors when typing them, and are easier to remember." In light of my previous comment about short labels for the statements, you might end up with: [Short URIs Are Friendly] Short URIs require less effort to type, are less prone to errors when typing them, and are easier to remember. This is not much longer than what you have and I think the rationale provided (likely imperfect as proposed) makes the statements much more meaningful.
