Yesterday VidMe launched their site choosing the tagline "Live Life, Share Private." The reported financial model is pay for service, not advertising-based.
It's interesting to watch what's developing regarding what we'll pay for online and what we won't... We're starting to see that, indeed, premium content can be worth paying for. As is extra functionality for the enthusiast membership base. And we'll see what happens to mass market news services.
Now we're seeing pay for privacy, a natural market result of small groups of friends becoming large groups of loosely affiliated people.
But with that privacy interface also comes some tertiary creative stuff such as group selection, organization, tribe creation and the collectively appreciated (and understood) moment or joke... All of which can make sharing a little more dynamic and, perhaps, even a little more fun.
Worth paying for? Sure, probably to some.
