* UberMedia, maker of of the Twitter app UberSocial, announced Chime.in, a new social platform centered on relevance and monetization for publishers. “Existing systems don’t really have a good way of pulling good content and putting it up top,” CEO Bill Gross told Fortune last week. Users create posts called “Chimes,” which can include images, videos, polls, and links and are shareable on Facebook, Twitter, and Google+. They’re easily sortable and searchable by interests, the people sharing them, popularity, and timeline. You can also choose to follow someone’s Chimes based on topic to winnow out content from the person that’s not of interest to you. Chime.in looks to address monetization by allowing current publishers like Universal Pictures, Bravo TV, and Disney to take 100% of ad revenues from ads they place themselves and 50% from ads that UberMedia places on the publishers’ behalf.
