I enjoyed Enid Blyton as a kid, read everything she ever wrote though the Secret Seven annoyed me. But in saying that I outgrew them and moved on and they did help with reading mileage and getting me hooked on reading. There are a lot of HP adult fans out there, and people who read a very narrow range of books. What really disturbed me was during an teaching lecture a lecturer who's specialist area is reading got up and went on about how the HP books are just wonderful and she wasn't meaning just to get kids reading.
