The insistence on avoiding monads by experienced Haskellers, in particular on avoiding the IO monad, is motivated by the quest for elegance.

The IO and other monads make it easy to fall back to imperative programming patterns to "get the job done". [...]

Often, the monadic solution _is_ the elegant solution. Please don't confuse monads with impure operations. I use the monadic properties of lists, often together with monad transformers, to find elegant solutions. As long as you're not abusing monads to program imperatively, I think, they are an excellent and elegant structure.

I have seen several libraries where all functions of a monad have the monadic result (), e.g. Binary.Put and other writing functions. This is a clear indicator, that the Monad instance is artificial and was only chosen because of the 'do' notation.
