I almost never re-read books. I suppose if it has been a really long time - like 15 or 20 yrs - and I loved the book, then I’m not against the idea.
This is probably because one of the things I love about reading most is not knowing where things are going to go. Hence why I like a lot of suspense/thriller type stories.
I don’t care about it being open source.

If he sold Sync, then my answer might be different.
