I do have ideas and it is a major breakthrough. And it likely won't get picked up on because I'm too low on the totem pole.
I joined a forum a few years ago at a time when I was very ill, doped to the gills and had major trouble "behaving" myself, so not at my best. It had been around for a few years and the owner whined constantly that he wanted to increase membership, especially international membership, and couldn't figure out how. I was there six months and membership began going up dramatically, especially international membership -- so much so that they eventually created some subforums aimed at the international members. But I don't think anyone really knew it was me that engineered it. I wasn't even a moderator at the time. You don't have to be a moderator to treat other people well. In fact, it probably helps in some ways if you aren't a moderator because then it is simply an example of a decent human being, not a person with a duty to set the example.
More recently, I joined a forum with 300 members and almost no discussion. After I joined, people began talking to each other. Last I checked, it had 1800 members and has probably become the Go To place for its niche, likely displacing a more long-standing group for that niche. Why? In part because I got thrown out of the long-standing place. The fact is that in some ways, where I am, that's where the action is. Except I'm not a hacker. I don't expect to be all that influential on HN. I come here because I get to be treated like a normal human being and people, oh, talk to me instead of dividing up between those that worship me like a rock star and those that desperately want to shoot me down and put me in my place. So I am content with being a Nobody on HN and I have diabolical plans to remain a Noboby on HN so that it can remain a decent social outlet for me instead becoming ruined for me socially like every place where I ever became Somebody and then after fostering discussion generally on the forum, I was the only person no one would really talk to.
Still, I'm compulsively helpful, I tend to care, I have this unusual expertise (or insight or some such) and it just annoys the crap out of me when I can't give it away. Maybe some day I will come to my senses and stop caring about others and just use it the way most socially insightful people seem to use their skills: As manipulative ass-hats, for personal gain, because they know something others don't know. But I'm not there yet.
Peace.
