My dear friend and former colleague John Carney will be joining CNBC.com as a "senior editor" in the coming weeks and will also be "appearing regularly on CNBC’s Business Day programming." Over the last few years John has been on the network as guest commentator but now that he's an official member of the team, one very important thing needs to happen. It goes without saying but here it is: a nickname. Maria's got one, Erin's got one, Phil LeBeau's got one and now Carney needs one too. If he's gonna do this, he's gotta do this right. I know what my pick is but let's get democratic about this. Serious suggestions only, please.
