There are a couple of blogs I've just come across and subscribed to. Copypunk - my colleague Jon Silk, who used to blog by the name Clogger, has moved to Copypunk where he'll be posting about life as a coywriter. And Brand Strategy - the blog of the magazine, written by Ruth Mortimer.
The World's Leading has just linked to a new blog too, by a Weber Shandwich chap by the name of Paul Wooding. The blog's called note to editors and you can see from Paul's about page that he's a former hack turned associate director as WS. Subscrbing to that too then.
