Oliver Reichenstein makes a strong case on why Twitter share buttons, Facebook likes, and Google Pluses are not so great.
Some people probably do use those buttons. Maybe even a lot of people. And maybe you do and think I’m dead wrong about this. Maybe I am. And maybe someone needs to do some serious research to know for sure. I won’t deny all that. What I know for sure is that most people who know how to use social media also know how to share URLs.
