Almost nobody reads the AIP
Private pilots tend to read flight guides (Pooleys, in the UK).
Serious private pilots (however you define that?) tend to use airport data in flight planning software e.g. Navbox or Jepp (which is in turn lifted from the AIPs, or other flight planning software).
Quasi commercial pilots use Jepp, plus airport directories like ACUKWIK, with heavy reliance on handling agents, etc.
Real commercial pilots don't read anything because they have an OPS department
I think pilots in N Europe are spoilt because their AIPs are reasonably accurate, but once you get to Africa (i.e. anywhere south of the Pyrenees or the Alps) the accuracy goes way down - but if you do something wrong, the national CAA is ever so quick to point you to some page in their AIP
