Michael Arrington at Techcrunch reports that video is coming soon to Flickr [1].
This is great news, and I think it could become an overnight major competitor to YouTube — having both types of media available via one site/service makes for a lot of convenience.
Though, people may not realize that it’s already been possible to a small degree, if you upload an animated GIF to Flickr (see this example [2] where I uploaded an animated sequence of a glider’s movement from Conway’s Game of Life [3]).
