Right - that means that instead of having a camera in whatever room Sean Patrick is in, and long stretches of dead time when he's somewhere that can't be wired for filming, you see Justin's environment all the time no matter where he is. Bandwidth also means that it can be streaming video rather than a web cam that updates every 20 seconds or so.
I'm not sure why this is supposed to be compelling. The presentation has changed, but the content hasn't. Or is it that the time is right, and there are enough voyeuristic people and enough revenue to be made from Google ads to make it worth doing?
I think there are a few reasons why this is compelling from a content standpoint: first, reality television has accustomed people to watching non-actors as entertainment. However, reality television has lost its appeal, as the contrived game-show aspects have worn on people.
Also, internet video has gone mainstream. YouTube + blogging + other user-generated content has just grown the appetite for watching everyday people do and say outrageous things. Add into this the presentation aspects (live, all day, wireless) and it becomes something different, unique, and compelling that, apparently, has a huge audience.
