I don't think that's really the case. When posts express substantive, thoughtful analysis or ponderings, it's OK, but many of the SFO posts in the past have turned into meaningless subjective opinion expression that isn't really that interesting. And that's been the case with many pro-SFO and anti-SFO posts. It's not really Jeff expressing bias against positive SFO posts (though we know his opinion), it's more that new or interesting ideas are rarely expressed, or quickly degenerate into pointless arguments.
I'm not particularly interested in anyone's opinion of any park, and similarly I don't try to force my opinion of any park on others. I judge a park's worth by the discussions of the coasters it contains.
