Yes, I re-read parts of mine, especially when someone lets me know that there's a error ^_^;...then I want to go back and re-check everything. I have to focus on sections at a time because it's almost 800 pages long and takes hours to re-read the whole thing. I do like my story and characters, so I enjoy re-reading it and getting immersed in the story again if I'm having a bad day.
I feel bad when I miss comments, especially if it's a question and I don't get a notification so I try and go back once in a while to at least the pages that usually generate the most questions.
Sometimes I cringe at the older pages and have a strong desire to 'fix' them, but I don't have time
and even if I 'fixed' them, they would look to out of place next to the previous and following pages.
