I think a title (like this one) that explicitly includes some of the topics covered is a very good idea. It hints at the fact that there are many short essays, which sounds a lot more inviting than if it were one monolithic work.
Also, this kind of title conjures up more concrete images in the potential reader's mind and seems more likely to generate interest than a more generic title. You're only going to read "The Methods of Rationality" if you're already interested in that topic. "Zombies to AI" (or "AI to Zombies") just sounds fun!
Quantum Computing Since Democritus got me thinking that we may want a more riveting title for The Sequences, 2006-2009 ebook we're preparing for release (like the FtIE ebook). Maybe it could be something like [Really Catchy Title]: The Less Wrong Sequences, 2006-2009.
The reason for "2006–2009" is that Highly Advanced Epistemology 101 for Beginners will be its own ebook, and future Yudkowskian LW sequences (if there are any) won't be included either.
