I did read back and look more than a few times. One was what I wrote when a person, wondering what I said then. Other times trying to see the first mention of an experience.
I definitely didn't go back and read sequentially though, because mostly I didn't do anything interesting day to day. But I've found that sometimes things stick out that I didn't realize when I was writing it. By the end of that stretch when I did write daily, I got very in depth because I was curious what would be of interest later.
