My intuition tells me that United Online, the parent company of NetZero, is about to gear up their marketing efforts, and also that Chairman/CEO Mark Goldston is layering the organization to look better to Wall Street.
The company, which currently specializes in dial-up Internet access and has some other Internet related properties has made noise that they plan to enter VoIP. My guess is with the new addition and the coming fall marketing season that we will be hearing something in the next 30-90 days.
