I didn't make it all the way to the end (insert irony here), but an initial reaction is that there's uninformed meta and then there's informed meta.

Or perhaps I should change that to "informing".

A little of either goes a long way. The former, as a sand trap. The latter, towards insight, efficiency, and pleasure.

I'm suddenly reminded of Larry Wall. Perhaps I might treat "meta" as a potential offspring of laziness. (E.g. if you don't enjoy repetitive, rote tasks.)
