My Acknowledgments Page

I've been reading a lot this semester.
I won't go into all the books I've read (yet). I'll just say that some I would recommend heartily and others....well, others I would suggest a little less enthusiastically.
But one thing I've noticed myself doing: reading the author's acknowledgments page.
I just finished a novel by Laurie Halse Anderson (Wintergirls) and her "thanks page" was actually three pages long--she even thanked her ex-husband and her ex's new wife. Reading that made me think of the funny comments in author Libba Bray's book that ended her trilogy. There were some random comments in there and a huge spoiler since I stupidly read it before starting the third book; it makes more sense for it to be at the end of the book instead of at the beginning!
But I'm also wondering whether these pages even get read--besides by the people who expect their names to be mentioned. Anyone else care that such-and-such thanked so-and-so for the fantastic copy-editing?
If BJ writes a book someday (which I'm sure he will--who knows whether it'll be the Beer Drinker's Guide to Wine or something more philosophically-minded, though) I wonder what line I'd get. What would I say in an acknowlegments page (even though I'm never going to write more than a few paragraphs in a haphhazard blog)? I guess it would be like writing an Oscars acceptance speech before you've been nominated. Silly. But maybe I'll write a blog post with a bunch of random thanks that only make sense to the people mentioned. Seems like the thing to do. :)
