[merely-unlikely]

Seems to me that any concern here is more around case discovery. Whether judges learn about cases from Wikipedia, Lexis Nexus, university publications, etc there is always a bias in which cases get surfaced. Wikipedia being more open than most other venues can be good (more contributors/diversity of viewpoints, easier to critique) or bad (more potentially unsophisticated/ignorant contributions). I tend to bias toward more open platforms given the choice.
