Hylton's got a nice little Blog innovation over at Corante [disclosure:: I write for Brandshift on Corante].
"...the intent of the Blink is to differentiate its content from the longer, meatier posts and to provide a space in which you can provide short pointers to interesting items/articles/blogs that don't require much commentary.
