Premature annotations for strictness is the root of all evil?  :-)

How do one find "good" places to use strictness annotations?  (Is using
a profiler the answer, just like it's the answer for manual optimisation

Oh, just in case you didn't guess it already, I'm a Haskell n00b who has

Software is not manufactured, it is something you write and publish.
Keep Europe free from software patents, we do not want censorship
by patent law on written works.
