One of the cooler things I've signed up for recently is a web service called Very Short List.  Every day they send you a new link to an interesting book, film, website, etc.  Examples of past interesting sites are Musicovery (a very neat internet radio site), a site that shows you the front page of every newspaper in the world, and a notice reminding everyone that one of the more interesting Making Of documentaries of all time was coming out on DVD.

I highly recommend signing up for this.  The newspaper site showed one of the funnier solutions to a real life whodunnit.  Can you figure out how the police caught the pickpocket in the bottom story?
