Developers are often That Guy because they foresee what will happen when they get to writing code; they realise all the thousands of small problems the work is going to throw at them, and they spew that out to their colleagues.

Foreseeing the problems is good engineering, but it can be a bad move politically to spend a lot of time describing the issues. That's what makes you That Guy.

It's a terribly quandary -- I have to stop myself from being 'a lawyer for the compiler', if you get my drift.
