A video is not a substitute for a written review.
I love GB video content as does probably anyone reading this, but a round table discussion will never equal a well-though-out written review. Written language can be much more nuanced than speech, especially when said speech isn't from a teleprompter. I am not illiterate. I don't consider reading a "chore". I don't go out of my way to avoid reading. It is still the best method of conveying information from one person to another.
Video reviews are a welcome addition to the site, but they should be exactly that. An addition, not a replacement.
