As a YACFer and AUK I naturally support Steve, but I'm really interested to see how what was succinctly described as "RAAM vs PBP" plays out. Which means I support Kurt as well - what he's achieving really is remarkable.
Other than the usual recumbent-bashing, and the odd bit of humour that might be lost in translation, I haven't seen anything that can really be described as 'trash talk', but there's presumably a whole bottom half of the internet that I've not been reading on Facebook or somewhere.
