I like footnotes because I don't have to flip through pages looking for it and it's right there at the bottom of the page! It's like a little treat in an already entertaining book! Not sure why more people don't use them. I think the most famous example of the best footnotes would be Terry Pratchett. His footnotes are always topical, interesting, and humourous.
And as this year comes to a close, I do have one other question, does anyone want me to start posting what books I read? Kind of like my own personal reading list, for next year? Let me know.
