That's a very good point.

Also a somewhat embarrassing one. My standard practice is to go to Wikipedia to find out what is going on, then back to the page to find out more. And yet, when I came across a good, helpful page, where that was not necessary, I didn't even notice.

I guess this is yet another example of good design being design you don't notice. (Although, obviously, that "you" isn't referring to you.)
