A while ago I met an older friend for lunch. I used to work with him years ago in my first job (failed startup). He was out on his own again building out an innovative idea he had in Smalltalk, (which is what he knew). I was talking to him about FP and type theory about all the debates that were going on about it. He just said that its a waste of time listening to most of the people on these kinds of sites because you can tell straight away that most of them don't build anything. Of course that's not quite true, but there was enough truth in it for me to feel like it was a friendly kick in the ass.
