Good point. I did make it up.
Let's take something like using the (now removed) + operator in Google search.

> However, we found that users typed the “+” operator in less than half a percent of all searches, and two thirds of the time, it was used incorrectly.
1 in 600 searches used it correctly, another 2 in 600 used it incorrectly.
Stuff like that.
Or have a look through /r/tipofmytongue for people looking for help to identify songs, tv shows, and films. You'd think they'd include details of roughly when they saw the film, or who any of the actors were (or even what other film they'd been in), and then the plot (with some details), or the name of some of the characters, any music, the genre of movie. But you frequently see people who give very vague information. I won't give examples, but it's really easy to find them.
But I do need to remember not to be a judgemental dick about it, and if I was I apologise.
