Thanks for the interesting link. I think the discussions used to be much better. There was less 'noise' and some truly excellent 'signal', 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'm not the first to say, in any community, 'it's not like it was in the old days'.
