Just a note to say that my Are AES 256-bit keys too large? post from July 2008 has been visited over 1,000 times this month. For the last few years it has been my most popular post by far, and I once referred to it as one of my Pareto posts. Probably what happened this month is a link to the post found its way onto some social channel, like Twitter, and just mushroomed from there. It just shows that content really has no use-by date in Web 2.0.
