John Carney, editor of the readable financial news and gossip site Dealbreaker (founded by original Gawker Elizabeth Spiers), is leaving to edit a new, similar site from Silicon Alley Insider called "ClusterStock." Caroline Waxler, formerly at MainStreet.com, will be heading up fellow SAI blog the Business Sheet. SAI itself is losing its managing editor Peter Kafka, who will be starting a new media and advertising blog for AllThingsD. And wrestling champ Alex "Blue States Lose" Blagg is leaving his blogging gig at BestWeekEver. See, jobs exist!
