Though I'm not entirely convinced that the "group" standard for publications here makes sense -- if it's a publication that's widely read, why does it matter if one person is making the lists -- it seems only consistent that Fast 'n' Bulbous be left off... I haven't scoured the site, but the whole thing is written in first person singular, and I think it's only one guy.

Furthermore, how do you decide to include Piero Scaruffi, Robert Christgau and Martin Strong?

This is difficult, but the Fast 'n' Bulbous, Scaruffi, Christgau and Strong lists/ratings are lifetime achievements rather than one-off articles.
