In my opinion (as a non Haskell user) pointfree style is less readable than the using the normal lambda syntax. In the latter I see at least for each step the amount of input parameters for a function and how they are used. With pointfree style I would need to look up which parameters a function consumes, and what the previous step actually delivers. Type systems at least make this safe, but I still think readability suffers, and the only gain is a bit smaller code.
