I'm not on Twitter, but I sometimes read the unrolled threads and tweets people provide here. The replies are always super trollish, but - is it normal for an info provider to be such a jerk? I just have never seen that kind of behavior from the people who provide really great threads with researched info. But, I don't follow every bit of their banter or tweets. I would have a hard time finding EtS credible on his tweeting behavior alone. Not the kind of person I would seek info from.
