I don't skip or skim when reading. If I find myself wanting to skip ahead then that usually means the book is not interesting and I'll consider DNFing it, or doing what I call a slow read. A slow read for me is a book I'll read in small sessions over a long period of time while reading other books at my normal pace.

I do believe that each of us gets to choose how we interact with books, and I try to stay judgment-free about how others interact with books and try to ignore if anyone has an opinion on how I interact with books.
