What counts as interesting?
It goes without saying that the word interesting is quite subjective. So by interesting I really mean interesting to me. Your mileage may vary. That said, I try hard to choose topics that, in my estimation, are unusual or unfamiliar to the average North American adult and seem likely to interest a wide range of people. In general, I try to select things that will still be interesting several years from now, which rules out many topics in the worlds of high tech, pop culture, and politics, interesting though they may be. I also prefer, when possible, to describe things with which I’ve had some personal experience, because I believe that gives the descriptions more depth and credibility.
What counts as a thing?
After an exhaustive lexical search, I determined that thing was the only English word suitably broad, generic, and vague to cover the entire range of topics I wanted to present. An interesting thing might be a gadget, an event from history, a philosophical concept, a word, a place, a food, or pretty much any noun except a person. Even there, I might make an exception now and then.

Where did the idea for Interesting Thing of the Day come from?
It all started with the Girolle. When I first encountered this simple gadget for shaving cheese on a vacation to Switzerland in 2000, I thought it was one of the coolest things I had ever seen. Although I was happy at the discovery, I was surprised and slightly annoyed that I had never heard of such a thing before. My next thought was that many people outside that corner of Europe were probably also unaware of the Girolle and would probably be equally interested to learn about it. I knew, too, that there must have been many other unusual things I’d come across in life that made me say, “Wow, that’s interesting!” in much the same way. All kinds of things: words, places, historical events, foods, and of course gadgets. I ought to create a Web site to share these fun tidbits with the world, I thought. I’ll call it “Interesting Thing of the Day.” Within a few minutes of my first encounter with a Girolle, the whole plan had formed in my mind. A few years later, after a fortuitous layoff, I finally had time to make it a reality.
