Recently discovered on twitter: Lee Clow's Beard

I had just about given up on Twitter for the 2nd time. My tweets have been inconsitent and lame (though not inconsistently lame) and I've generally found little value. Though I do know the exact travel schedule of many a branding exec. Which is obviously helpful.Then I came across Lee Clow's Beard. It's a steady flow of insight of the "wish I said it that way" variety. Today's: "Most people don't have enough time to interact with their kids, let alone your brand. Respect that."Who on Twitter do you find uniquely worthwhile?mj
