Found almost immediately on the blog's about page:
TVNewser has been named one of the most influential blogs in television by the Wall Street Journal and The New York Times. Upon graduating from Towson, Stelter took a job with The New York Times in July, 2007. That month TVNewser's new editorial team was brought on board: editor Chris Ariens, a 15-year TV news producer and manager and contributors Gail Shister, one of the foremost Television reporters in the country and Alissa Krinsky a Chicago-based former news reporter and anchor. A few months later, former Fox News Channel production assistant and NBC page Steve Krakauer joined us as our associate editor. Steve moved on in June, 2009 and in July we welcomed Kevin Allocca as our new editor.  This more than makes the case that they are professional journalists.
