In the last decade, I think I've only used it to find version numbers. Here's an embarrassing(?) example, though: I was typing a response in this post and I wanted to italicize a word. I know different systems have different ways to do that, so I just guessed and tried <i></i> like in HTML, which I learned in fourth or fifth grade. No go, which didn't surprise me because nothing takes HTML input anymore. So I tried [i][/i] as if typing a message on a phpBB forum. No go. So I clicked to edit the post again and just surrounded the word with /slashes/ to indicate it was italicized in my mind. And then I noticed the little tiny help link next to the text box and clicked on it. Help, to use italics? Lame. But it worked (see what I did there?). Here is something interesting: that help link doesn't show up for an initial comment, only if you go in to edit it.
