Twitter said to have acquired fledgling video-sharing service Vine

Twitter has pretty much nailed text-based interaction, so it looks like it's time to diversify into video. According to AllThingsD, the blue birdie has snapped up a three-man outfit called Vine, a video-sharing startup intended specifically for bite-sized clips. You'd be forgiven for not knowing it - the service hasn't actually launched yet - and there's no word on whether it'll operate independently or be assimilated by the social network.
