One of the hosts on the Crate and Crowbar podcast is a former Edge writer, and at some point he brought that up as a general positive because it allowed him to write more freely about what he personally felt about the game while setting aside general expectations and such. Paraphrasing from a segment I listened to years ago, but that was about the gist of it. That's probably in part why Edge scores don't always follow the general consensus.
That's a fair point. I can understand how it's a bit more liberating not having your name out there attached to a score for people to attack on social media.
