Every so often I trawl the most common entries in my website's referrer logs, just to see if anyone interesting is linking to me (and what they're saying about me if so).
Makes sense in retrospect, of course; TVTropes touches on video games, so why shouldn't they link to a video game I wrote? But it surprised me at the time; it would never have occurred to me that a site I mostly associate with commenting on plot and characterisation and setting and so forth would be remotely relevant to anything I've done.
