We love to get rid of links off the navigation bar. It just feels so...liberating. :) It's a rare occurrence that we get to do it, but this is one of them. There used to be two links on the right side of the nav: "Manage questions" and "Ask a question."
With the introduction of our new discussion capability, things were getting tight. We also felt like the "manage questions" link was pretty redundant with what's already in the "questions" link - the only thing missing were a couple additional sorts to show you your pending or submitted questions.
