Two of the blog advertising industry's three major godfather figures, Jason Calacanis and Nick Denton, are publicly arguing about ethical standards for blog journalism. Calacanis's tech blog turned down a junket offer from Siemens, while Denton's Gizmodo accepted the offer, highlighting the debate among bloggers over whether or not they should adhere to standards - like no freebies - mainstream journalists purport to observe. Poynter Online notes that some bloggers feel the behavior of other bloggers rubs off, for good and ill, on the whole group, leading to self-policing verbal spats like this one.
