I haven't been here long, but every forum has their share of BS with the good. Also what forum doesn't have some advice that is biased or off base and didn't work out when you tried it? I think that is to be expected.
I am on here to learn, but on other forums I am on there for people to learn from. There is some advice I shrug at because I know better on the topic. Doesn't make the place awful, it makes it a forum. Planted tank is not much different. I am also on there...I'm on a lot of forums, actually. Haha.
