But if the notes are long and/or numerous, they can interfere with the flow of the text. Eg, the wonderful Penguin eBook of Jane Austen's "Pride and Prejudice" (an example to every publisher of how to produce a good eBook) has many notes in each chapter, and many of them are long. If I'm reading it, I wouldn't look up a note on what a "chaise and four" is, because I know what it is, and I wouldn't want to see the half page of text on it in the middle of the main text either.
In the case of this particular book, by the way, even in the printed book the notes are endnotes, not footnotes. If you have a few words, a footnote is fine, but if you have a page of explanatory text, an endnote works a lot better.
