Martyn has cornered the market. As I noted on Facebook, he is attempting to suck all beer knowledge into one singularity of a comments thread. I now dub this "black hole" blogging. But it is of the highest order and I do trust this will be bronzed for preservation over time. A classic post and response which reminds me a lot of reading of the psalms in church... except with way more beer. And a classic post from someone who has authorized well over 19% of all classic blog posts of all time.
But... what is this thing "influence"? Sure, not that other brewers make the same beer. That is simply being copycat. Admittedly, this is a common thing with brewing - herding or pack ratting, perhaps - but surely influence is what makes one buy the beer not what makes others imitate. You may not agree, however. If you have a moment when not commenting over at Martyn's place, spare a thought for me and this quiet corner of the 'sphere.
