Reuters media reporter Robert MacMillan is leaving the wire service for what we're assuming is a bigger payday at Rupert Murdoch's Wall Street Journal. In an email to colleagues, he writes that he's becoming "their publishing beat reporter, which means I will continue to write about the business of and the future of journalism. I have no contact information yet, but will write when I do." He starts February 4. And we're expecting a Plaxo update before then.
