There's this one user, a Google zealot - we don't know who he is - who occasionally sends an e-mail to our "comments" address. Every time he writes, the e-mail contains only a two-digit number. It took us awhile to figure out what he was doing. Turns out he's counting the number of words on the home page. When the number goes up, like up to 52, it gets him irritated, and he e-mails us the new word count.
