Definitely my vote for best April Fool’s, BoringBoring, a parody of BoingBoing. A few months ago, Erik had a great idea to do a parody of Boing Boing, which we thought we’d call “BoingBoingBoingBoing” (slogan: twice the boing!), but neither of us had the time to do it right. These guys did.
(Side note: favorite post has gotta be the explanation for the increase in blog posts.)
