can be found here. All of us at VC have done 0. I hope we've avoided 1, but I'm not sure. Most student note work is 2 or 3, but so is a lot of professors' work. I've mostly done 4 through 6, with forays into 7 and limited incursions into 8. Competent 9 and 10 are beyond my reach.
UPDATE: I've corrected the title of this post to reflect that the linked post on legal scholarship appearing on Jim Chen's Jurisdynamics blog was actually written by Professor J.B. Ruhl. It makes for a catchier title, anyway. (Thanks go to Ryan Scott for the catch.)
FURTHER UPDATE: Professor Larry Solum has an interesting critique of Ruhl's Rules here.
