On Saturday, Eastman Kodak Company CMO Jeffrey Hayzlett told Midem music conference attendees that the company now owns a stake of Twitter photo-sharing site TweetPhoto . Hayzlett’s exact words on the deal were that the company liked the partnership it did with TweetPhoto in November, “so much so that we took a piece of the company.” The terms of the deal are still unknown at this point, but sources close to TweetPhoto tell us that the arrangement was made at the end of the November. According to our sources, Kodak currently owns stock warrants in TweetPhoto, which are securities that entitle Kodak to buy TweetPhoto stock at a specified price, though that price has yet to be publicized

Until today Twitter officially prompted you to share the answer to the question, “What are you doing?” — which over time has become only one of the many ways users have chosen to create status updates. To address the diversity of use cases Twitter now sees, the company just changed the official question to, “What’s happening?” On the surface it’s a minor change, and yet it’s significant in reflecting the shifting focus and user behavior of the service over time. As most users know, the official question is largely ignored by those who have found myriad ways to share pretty much anything they wanted, be it information, relationships, entertainment, citizen journalism, and beyond.
