Valleywag was waiting for the first gripes, from investors in Digg, to the rumor that the social news site's hyperactive founder was moonlighting on yet another business. Kevin Rose was reported by Gigaom to be developing some kind of instant message program, a rumor which would be supported by his recruitment of Windows application developers. There's no word from David Sze of Greylock, Digg's largest financial backer, but another investor seemed relaxed about the Digg icon's entrepreneurial philandering. "As long as Digg keeps doing as well as it is, and Revision 3 keeps doing as well as it is, more power to him. It's unconventional, but hard to argue with success." Damn. Another potential scandal fizzles out.
