All this is true, but I think alumni groups like I mentioned could actually add as little stability and consistency to the quality of university groups. My parallel could be something like the Oxford or Cambridge Union or a range of university associations or clubs. The management changes every year but they maintain quality and prestige. That model could transfer to EA groups too to some degree, especially once they have gained some pedigree after being active for 15 or 20 years.
