The new platform, a "brand enthusiast gallery", will house brand-related tweets for companies to choose from. Twitter will apparently get in touch with anyone who tweets something that a brand likes, and ask for permission to repost it. Engadget's sources have confirmed that the gallery tool is already being tested. Speed and simplicity are apparently two of the points Twitter is looking to promote. As Digiday reports, advertisers are already using celebrities and Twitter users with substantial followings to promote products inside Twitter. These are usually handled by third-party agencies, but if the new tool happen, it could pull some of the advertising power back to Twitter -- and away from Big On Social Media stars.
