I really wish there were an edition with the footnotes inserted into the main body in some clean way. Like a quarter of the book is in those notes and many plot critical segments are buried back there.
Also there are multiple endnotes that you read more than once, so I'm not sure putting it in text would work.
Some footnotes are chapters in themselves (or have their own footnotes), and I couldn't shake the feeling that the confusion I felt upon realizing that I had still been in 'footnote territory' was entirely intentional, similar to his run-on sentences that have a very specific effect. I rather liked how reading an ebook version made it even easier to forget I was reading footnotes.
Also, one of my favorite jokes wouldn't work if he'd put the footnotes at the bottom of the pages.
