Assuming "they" refers to Albertans, who knows? But there's a bell curve in this world and some people happen to be on the left side...
Am I incorrect though? A board that only has positive reviews is absolutely useless. There would be no need for reviews. The only thing the board would need would be ads. I see an ad for provider X, I go see provider X knowing all reviews will be positive so no point in reading them. I have a bad time with provider X, I note that my bad review has disappeared, so I just move on to different providers and it becomes a gamble.
I was hobbying long before joining this board. Admittedly it was a gamble. Had some great experiences, had some okays, had some not-so-great ones.
