After falling out with the micro-blogging service, the company formerly known as UberTwitter may go it alone.
US firm UberMedia may be planning to launch its own rival to Twitter, according a report on CNN.
Citing three sources, the report claims that UberMedia's new social network will address 'common complaints' about Twitter including "its restriction on the length of a message and how it can be confusing to newcomers".
UberMedia currently bases much of its business on Twitter, through apps including UberSocial, Echofon and Twidroyd. The company used to be called UberTwitter, until a recent row with Twitter led it to change its name.
Twitter had blocked access to UberMedia's apps claiming that they were violating its policies. However, the company has declined to comment on the record about plans to hit back with a potential Twitter-killer service.
Can such a service succeed? Twitter's momentum makes it a tough call, but then a few years ago, people might have said the same thing about Myspace, which has since been eclipsed by Facebook.
