I don't exactly understand the "Giving back to the Community" theory but who would reveal their money making secrets and invite competition to their own campaigns and projects?
It's not quite what your thinking, very few give up there niche markets and exact "current" income sources or strategies, nor do you have to in order to give back to the community (so to speak).
What is of value are the tips, idea's, thought's, strategies we've learned that can be applied across any market or can be applied across a wide variety of markets with a little tweaking.
Everyone always want's an exact do this and you'll make $xx,xxx type of formula but in reality things like that just don't exist. You have to be smart enough and willing enough to learn some things for yourself but also to adapt and try new idea's that might have been sparked by the thoughts, strategies and similar workings other people are doing or have done in various markets.
Basic point is, your never expected to reveal your exact niche or exact strategy so people can copy you and steal your income sources, the community sharing thing is about sharing certain details that come from years of trial and error as well as vigorous testing and figuring out how to incorporate those strategies and/or idea's into your own business model.
Heck sometimes one person's failure's turn into another person's success, for instance someone can share an idea that failed them and someone in another market comes along, gets an idea from that failure, tweaks it and earns a bunch of cash. I've seen that happen quite a bit before.
Anyway I'm hoping you see the difference by now, having a community to be part of isn't always about giving away your exact niche or data that you have it's more about tossing idea's and strategies around, and so on.
I feel as if in the earlier day's Wickedfire had that type of community atmosphere that simply couldn't be found anywhere else at the time. But eventually over the years just lost that flare so to speak.
