Also to be fair, there would be no Vine without Instagram, it is almost an exact duplicate interface, with video instead of images.

To be fair, it's really not like Instagram had never considered doing video up until Vine came out. Hell, I'm sure every high schooler had the idea of "Instagram for video"; it's a very accessible, logical progression from Instagram-style photos.

Vine didn't invent mobile video.

While this is true, you can't deny that what this article is showing is almost exactly what was innovative about Vine. The short, hold-to-film, no edit clips originated with Twitter's product.

That being said, I'm not excited about this update. I love Instagram, but mostly for it's simplicity; the number of vines on my Twitter feed worth watching is astonishingly low, and this will only produce, IMO, more content not worth watching.

This isn't generic "mobile video". This is short video clips, pretty much the same as Vine is doing.

From the video it appears/appeared that the capture interface/method looked to be the same as vine. Not sure who else did that before Vine.
