Not ten minutes ago I had the same experience in a web browser on my desktop; it turns out that on this site, which I've been visiting regularly for years, there is a button (unlabelled) which brings up extra content related to that day's content. I only discovered this from a passing comment on a forum. My point is, it's not just touch interfaces that suffer from this assumption that the user will "just get" the thing you thought up in the shower this morning. Even a console application needs that moment of sanity checking - more than once I've sent out a script to users and found out weeks later that the one cool timesaving feature I was proud of just hadn't been used, because I hadn't told them about it, assuming instead that they'd connect the dots for themselves.
