As a newbie, I'm much less inclined to altruistic considerations like what I can add to a forum. I'm much more interested in what I can get from the forum. If the forum has useful information, funny chatter, then users will share something one way or another. And long discussions about how to make the forum better and that newbies in the good old days were better are not as inspiring as those who write them think.

There's nothing wrong with that. I appreciate independent thinkers who can demonstrate original thought. The problem as I see it is the dynamics of the forum have shifted completely to the point where the only reason people sign up anymore is to join a campaign, or a bounty, or a second campaign or bounty (or 3rd, 4th, 5th, etc.).
When I first joined, signature campaigns weren't really a thing. Well they were but I'd say only about 30% of the forum participated in them. I was drawn here because I was seeking info on a now-extinct coin, but I'm glad I stuck around as I've learned a whole lot in the process. Nowadays people aren't interested in learning about bitcoin, crypto or the blockchain so much as how to get merits and write posts that can just barely meet their campaign requirements and won't get deleted as spam.
The stuff that I learned from having an open mind and
wanting to learn allowed me to create more wealth than any sig campaign ever could. There's a lot of ways to make money here; campaigns are just the most obvious one. There's several better ways, peeps just have to want to find them for themselves.
