In no particular order....
Normhead, for his fearless telling-it-like-he-sees-it. And excellent field photos.
Rondec, for his well-considered, sensibly moderate opinions. And wonderful rural landscapes.
Monochrome, for the insights into how businesses actually work.
Clackers and Digitalis, for flying the Aussie flag with common sense and knowledge.
MikeSF for almost single-handedly selling the idea of medium format to me. Bastard
And all the "Single In" crowd of course, even though I have been rather patchy there of late.
There are (several) others. I'll re-visit as appropriate.
