How can you tell if someone is doing things intelligently?
Fair question, but difficult to answer in brief, I might try to do this later. For now let me answer with a couple of questions:
How can you tell if someone is playing a guitar well?
In general, can YOU tell the difference between someone doing things intelligently, and doing things unintelligently?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
(I plan to make these threads from now on. Downvote if you disapprove. If I miss one, feel free to do it yourself.)
