I've trained specifically on this by reading thick books of prose like Ulysses,Dhalgren,Gravitys Rainbow etc. where the context is more important than the specific meaning of a sentence, the goal is to try to read faster than I can think, and then parse the information when I have more context. It's also possible to read too fast for any comprehension at all, and then slow down a little and take advantage of speed-blindedness - you'll read faster than you did before.
One thing that slows down a reader is focusing on individual words. Try instead to focus between two words, and use secondary focus to pick out the words next to it without re-focusing.
My own reading of Joyce is mediated through Paddy's Irish, Schubert (Winterreise), and Traviata (Bloom's solo). Music preferably from acoustic recordings.
Seriously, is there a distinction to be made between reading for facts/information (skim, scan, locate, focus) and reading as art (micro scale language and music in the voice, macro scale navigation of the plot)?
Does this distinction translate onto the Web? Is there a literary role for hypertext (pace Mark Bernstein)?
