I feel the same about those silly "Pin it", "Follow me" icons on every webpage. I cannot say that it has never helped any site get more traffic but for the most part it is just monkey copying monkeys all the way down. They do nothing except make all pages look generic and cluttered. The biggest example of just doing it for the sake of it is the porn sites that use these share icons too (who in the world shares a xxx video they watched on their facebook timeline?)
