It makes it conspicuous where everything begins and ends, you don't have to

I don't think I understand the question, you write it the same way you
normally would, you just replace some do/end with brackets, where they make
it easier to follow. The criteria are subjective.

I'm not sure what you mean by an editing trick, presumably you're thinking
as Marnen did, that adding a level obligates me to swap anything back and
forth. I don't consider that to be the case, it's not a rule, it's just
something I do to clarify my code, sometimes I find two do/end pairs between
every bracket is easiest to read, it just depends. But if you're in
TextMate, you can do ctrl+{ to swap back and forth. It seems to work okay,
but is a little buggy, so I don't use it often.

Whichever makes the code more readable in each situation.

I tend to use braces/{ } in functional-style code and do/end in
imperative-style code.

For example, I usually use braces with
Enumerable#map/select/delete_if/find/sort, and do/end with
Enumerable#each, File#open and Thread#new.
