Twitter Tops Social Media Buzz List

Zeta Interactive, a digital marketing agency, recently released its annual rankings of social networks. They are categorized by “buzz,” a ranking calculated by volume and tone (percent positive ranking) of all the sites. This year, Twitter topped the list followed by LinkedIn, YouTube and Facebook. Google+ did not make the top 10, partially due to its June launch—data starting from January 2011 was used to calculate the scores.
