Two acquaintances of mine, both teachers of one kind or another, tell me that they no longer feel comfortable steering students away from Wikipedia, because they can no longer maintain the prim pretence that they themselves aren’t consulting it on a daily basis.

I’ve long appreciated Wikipedia for its convenience; and been amused by its unforgivable mis-prioritisation. On the other hand, I’ve been irritated by the scrappiness of articles on concepts I’ve taught and saddened by the thoughtless pasting of its content into some of the essays I mark.
