Call it the Twitterfication of social sharing.
As if it wasn't enough for Twitter to limit our bursts of inspiration to 140 written characters, it has now rolled out Vine, a video-sharing app that limits your videos to just six seconds.
What can you do with six seconds of smartphone video (which, for now, is available only on iPhones, causing an aggravated Android Nation to again wail and wait)?
Not re-enact "Lawrence of Arabia" using action figures. That would take 2,270 Vine posts, give or take. Nor can you document a successful rodeo bull ride; those require at least eight seconds.
