Futility Closet has been one of my favorite sites over the last year. Check it out.
The site and its content are a bit tough to describe. It’s trivia, but it’s more than that. It’s logic, puzzles, trivia, history, quotes, chess, and much more. The nature of the site and the brief posts make you want more. So you click on Random Item, or follow one of the tags (e.g. History, Oddities, Humor) deep into the site.
The site’s author, Greg Ross, has a book out by the same name that’s a bit of a “best of.” Definitely grab it if you enjoy the site.
He was also recently interviewed by Boing Boing.
