Meanwhile, it would be probably be worthwhile if people would write about any improvement they've made in their ability to think and to convey their ideas, whether it's deliberate or the result of being in useful communities.

I'm not sure that I've made improvements myself-- I think my strategy (which it took a while to make conscious) of writing for the my past self who didn't have the current insight has served me pretty well-- that and General Semantics (a basic understanding that the map isn't the territory).

If I were writing for a general audience, I think I'd need to learn about appropriate levels of redundancy.
