I have lurked in rbr occassionaly for 7 years now. What I have noticed is a gradual decline in quality of the posts,and the groups in general. The Critpro, Magillagorilla and other anonymous obnoxious flame throwers have basically taken over the group. There is very little lucid and compelling comments left.
Brian Lafferty is left to defend his opinions against many illadvised losers. Carl Sundquist still does a great job. Jobst Brandt long ago quit posting. Bruce Hildensomething gave up years ago. Adam Meyerson basically has quit posting. K.Papai's postings have lost their punch. Kunich, as grumpy and opinionated as he was, has quit posting. On and on .... Most of what is left is the reactions to trolls. What a waste of time.
I would like to propose a new group for those types. It would be called rec.bicycles.kneejerktrollers
