I wonder if that's got anything to do with all the Army WO1's on my resettlement course who were planning on going outside to become security guards, tree surgeons and gardeners! or the TNA course I did last year where every pongo older than my son was a WO2!
RR and Bottom are significantly different. The results are also surprising with regard to rank weighting. My pecking order for reasoned and enlightening debate is; Pprune, RR, Arrse and eGoat (actually, never go there). Also, Arrse is great for a good squaddie humour laugh but the daily number of new threads is truly overwhelming!
I think you're very very wrong on enlightened debate on ARRSE. Debate in the Current Affairs board quite regularly made it to the house of lords, it gave birth to BAFF, and has a lot of 'great and good' users. Rum Ration is overall more serious, but the debate on it is definitely not.
