"If somebody starts talking about stuff like lines count, function sizes, nested ifs depth and tries to define optimal values, then be very careful about their advices" - me, ¤tYear
Regardless of what you think of this particular maxim, one could do worse than cargo-culting Linus.
Code org itself is IMO fairly trivial. I just do whatever I think happens to look good. But trends will emerge even when you're just coding to taste. Thumbing through my code I find very few instances of either `} } } } }` or `)))))` (disclaimer - I don't use lisp).
