I only joined a bit over 4 years ago.
I hope I've added something.
I do know I've learned a lot, especially about stuff I don't usually see and often don't look closely at because I simply can't afford it.
This board can be a harsh place. Most people here will give someone a chance, but there's little tolerance for any sort of shenanigans.
As someone who mostly deals with cheap stuff, It sometimes might seem a bit uptight. But then I consider that the fake item might sell for thousands and it makes a lot more sense. If I buy a card for $5 and it's fake or shilled I'd feel bad, but chalk it up as something learned. If I had bought one of the fake Magies I'd really have a problem.
I don't agree with everyone about everything, and that's something I actually think is good. But I also don't buy the common internet concept that everyones opinion is equal. Some of the people here were dealers before I started collecting, and have handled multiples of cards I'll probably never own. Some people only started recently (Welcome to the asylum !

) I know whose opinion I'd give more weight. But I would at least read all of them.
The same goes for people in some professions. I'm always baffled by someone who questions a solid opinion by for instance a lawyer discussing law unless they're in the same line of work.
I'm not particularly shy about expressing an opinion, and sometimes I'm wrong. I think a big part of having strong opinions is being able to change them when I'm wrong and being able to say "I was wrong" Of course I also tend to state things in ways that a lot of people don't get. (Seldom any absolutes, and a sliding scale of how sure I am)
And I'm rambling.....Sorry, I'm still working on that. Probably always will be.
