UberMedia Continues Shopping Spree; Buys Social News Platform Mixx

UberMedia (formerly known as PostUp and TweetUp) is on a serious shopping spree. In the past two weeks, the company has acquired Twitter client developers EchoFon, and UberTwitter. Today, the company has announced that it has acquired social news startup Mixx.com.

Mixx’s apps allows brands and users to curate social content into channels of information. In 2009, the startup launched TweetMixx, as a Twitter client that allows you to easily discover the links and content your Twitter contacts share.

The company most recently launched branded channels, which basically let brands, celebs and companies consolidate their Twitter traffic and mentions on one page. The tool also serves as a tracking and monitoring tool for mentions and conversations about a brand taking place on Twitter.

Last week, UberMedia announced the third rebranding of its service. The startup now offers a variety of third party services that are complimentary — and in some cases, directly competitive — with the clients that Twitter offers. UberMedia was originally called TweetUp, but changed its name last summer to PostUp as it added support for Facebook and LinkedIn.

UberMedia says that it plans to add Mixx’s channels to its family of apps, including UberTwitter, Twidroyd and Echofon. So with the addition of Mixx, UberMedia now offers users a social news and content curation tool.
