Someone had the bright idea to cross Twitter and Zite, and the result is Wavii. The service allows users to follow topics and then scours the web for news surrounding those topics, whether it’s a celebrity breakup or the latest statistics or opinion pieces on the upcoming Presidential election. Wavii has just launched publicly and has both a Web interface and an iPhone app. (Note: the service uses Facebook to register and sign in)
