Open Letter to some of our Thought Leaders (regarding bashing)

Open Letter to some of our Thought Leaders Dear Thought Leader, I really appreciate what you did for our community and the progress of our industry in general. But sometimes I am puzzled.

You don’t have to bash other ideas/persons to make ...

But I prefer a simpler mechanism and just adding impediments to the existing Task ...
