It doesn't. ;-) You now need to download Adobe AIR, Twitterific, TweetDeck, Twhirl, Spaz, Seesmic Desktop, etc, sign up with bit.ly, cli.gs, tr.im, learn all the #tag, @person stuff. Figure out how to autopost your blog posts into Twitter and Twitter status into Facebook, and all of them into FriendFeed and out of PixelPipe. At least, after all that, as a humorist you will be able to produce something interesting in 140 characters (or whatever the limit is) or less.
