I dont agree with this. Just because semantic(or any other tool) does not work for you does not mean it should not exists. Semantic is a massive time saver as a small team trying to build a functional product, where the team cant afford to have a pure front end focused developer. As a 2 person team, I can get a lot of functional product out with Semantic. I would recommend semantic any day.

It might not work for you, but like I said, it does not mean it should not exist. Thats me trying to defend a framework that I absolutely worship.
