I usually don't name them — just put numbers. As a reader, I like both. Chapter titles can be fun, if well thought out, but depending on the sort of book (fast-paced urban fantasy, thrillers, etc) I find them unnecessary as they can break the flow if I'm really caught up in the story.
I can attest that HB does indeed write great chapter titles. So does @The Bluestocking! I think they work particularly well in books that have a bit of humor to them, like Rick Riordan's Percy Jackson series. (He actually starts each chapter of his Trials of Apollo series with a haiku, which is next-level chapter title work!)
Awww! Thanks, Ju!
Honestly, I think you're on to something there with chapter titles working well for books with humour. A good title helps set the mood for what's to come as well. I love writing titles though - the appropriate title will also keep readers' curiosity hooked.
