As for the chapter summaries, I'm personally not a fan of them from the reader standpoint because I find that when I click on a story with chapter summaries, I naturally start to skim through them, and then I feel like I know what the entire story is going to be like without even opening one of the chapters. That's not true in all cases, but it is when it makes the story look really formulaic, and then it doesn't look all that appealing.
I think if I had read the story already, I would like chapter summaries better because it would help me track down my favorite parts, but for the first read, I don't like them.
