WebNewser parent mediabistro.com doubled its pleasure when it comes to covering Twitter, announcing its acquisition of Twitter analysis and commentary blog Twittercism.com from Shea Bennett, who will remain on board. Twittercism.com joins AllTwitter, which mediabistro.com launched in November.

Alan M. Meckler, chairman and CEO of mediabistro.com parent WebMediaBrands, said:

Shea Bennett has been covering Twitter for more than two years on Twittercism.com, and we will now combine his well-known analysis and commentary with our blog AllTwitter to create what we believe to be the most complete coverage of the evolution of Twitter and its rapidly expanding social-media business model. We are excited to continue building on our leadership in covering the huge growth of social media through our various social-media blogs including All Facebook, SocialTimes, and AllTwitter, as well as our SocialTimesPro research service and social-media events.
