Thanks for the interesting link.<p>I think the discussions used to be much better. There was less &#x27;noise&#x27; and some truly excellent &#x27;signal&#x27;, which made the discussions worthwhile. Recently, my impression is that the noise has significantly increased and the excellent signal has almost disappeared. But: That could be simply my mistaken impression, it could be just normal variability, or it could be something else. Certainly I&#x27;m not the first to say, in any community, &#x27;it&#x27;s not like it was in the old days&#x27;.
