If I'm browsing a library, then I have some idea what I'm looking for, what the context is around what I'm seeing. Here, I'm not looking for anything in particular, just browsing around. I have no idea what this thing is right away, and whoever designed it didn't bother to make it clear. There's a million other things out there that are clear right away, so why should I bother to figure this one out?
