"Phrase : Phrase" talk titles are almost always bad.

Usually, you end up with those because you couldn't figure out a good title (it's hard!) and decided to glue together a couple of clever-sounding phrases with a colon. It doesn't actually work, and hurts your acceptance chances/attendance.

Generally speaking, if you find yourself putting a colon into your draft talk title, rewrite it.
