Tweetie, the uber-popular iPhone Twitter application, has a big desktop brother called Tweetie for Mac that's just been updated to version 2.1 and one of the cool new features is support for adding video via the yfrog service (which previously handled static pictures).
iPhone 3.0 contains code that pretty much confirms we'll be seeing video recording, editing, and sharing if not in the iPhone 3G then certainly in the next-generation iPhone expected to be announced on June 8 at WWDC 2009.
Put these two together and what do you get? The potential for not only a pocket video explosion, but a pocket video micro-publishing explosion as well.
A 4K (2160p) RED ONE camera might be drool-worthy, but even most pros won't have it with them 24x7 when they chance upon that one great serendipitous moment. They might just have a video-enabled iPhone, however.
Likewise, sharing that video via MMS, email, or MobileMe, even YouTube is okay to great, but to immediately be able to push it out to all your Twitter followers? (Which suffers not the walled garden of Facebook).
Yeah, we live in interesting times!
