Just to do a drive by posting as I am only at the computer for 5 minutes.
It would just be lunacy to suggest that CAMRA has stifled development of English beer, a healthy question is always what more can it do though. I do wonder if promoting pubs to serve a craft beer that they know they can store for a long time where they will never sell enough RA is a good attempt at providing a gateway drug. No axe to grind either way, without a doubt a line has to be drawn somewhere and it more than makes sense that they stick to their definition of RA, but I just found that one an interesting proposition.
I do also feel there is that sniffy element, but I hesitate to bring that up because it runs the danger of taking "Kevin" seriously and I really wouldn't want to tar CAMRA with him.
Edit: Before I get pulled up on it, I very deliberately used past tense in this post, and it was intended that I was using present/future tense in my earlier post.
