Google's plan for a connected home including Nest and Dropcam lost a few family members today. Nest's Vice President of Technology Yoky Matsuoka and Dropcam cofounder Greg Duffy have left for other ventures, according to The Verge's sources. Matsuoka's joining Twitter while Duffy's next move isn't known at this point. Nest and Twitter, for their part, offered us an official "no comment" when we asked for confirmation of the departures. Matsuoka's Twitter profile looks relatively new, with her sole two follows being Alex Roettler and Dock Costolo -- Twitter's VP of engineering and its CEO, respectively.
