Maybe the medium, which is just a couple days old, has rough content now, but its format and contraints will likely create a new field of creativity. I personally don't like watching video streams because they're...boring. With Vine, and vinepeek, the banality only last six seconds. And some people are already mindful of the creative process they can apply (I saw a pretty cool taxi cruising down Tokyo in the night, as interesting as any movie scene).
But frankly, I like the banality. Sure, I see banality through my own eyes every day...but seeing "normal" as it exists for a Midwest mom getting ready to go shopping, a 20-yr-old dude wrapping up a joint, a 50-year-old guy watching Saturday morning cartoons....I dunno, this is just a few steps from being a very cool (if pretentious) modern art presentation.
As a photographer, I'll admit, I've never understood the appeal of video snippets (outside of those that show earthsattering news events, such as the snippets from the Arab Spring) over what can be conveyed in a split-second, defined image. But for the first time, I'm kind of seeing how much more potential expressiveness there is in six seconds of "moving" pictures.
