Snoop Dogg has a channel on uStream.tv called "Snoop Dogg Live". At certain points throughout the course of a day, week, month (depends on Snoop's schedule, I guess), you can watch Snoop go through portions of his life.
What's interesting (and potentially disruptive) is that by using uStream.tv as the platform, Snoop has essentially become his own social network. By tearing down the wall that most performers of his calibre build up to shield themselves from the public and becoming transparent in his day-to-day life, he's attracted people to the uStream landing page. What's very interesting is that the uStream platform allows more interaction with comments, followers, and direct Twitter posts -- people are interacting with each other even when Snoop is not broadcasting live.
This is easily emulated and my guess is that we will see more of this with other celebrities and artists. The artists that are successful in the future are the ones that can get their fans to subscribe to them, and they will like be able to monetize the subscription; the price the artist pays is transparency and exclusivity for those that are willing to subscribe (and pay).
Note that Snoop participates on a lot of other social networks as well (Facebook, etc.) and also has his own community hosted on his site -- uStream is just a very interesting example of the power of artist transparency.
