The Dialectizer has been around since the Neolithic Age of the internet (1998), so if you've been around a while you may have seen it. But it's sure fun to play with. Just give it the URL of your favorite web site and tell it what English dialect you'd like it translated into.

I find, for example, that my own site reads better when translated into Redneck, and the Postmodern Politics website reads far, far better when run through the Cockney filter.
