Thanks for the link, but I would be very surprised If the majority of people on this forum would go this route (link in OP) simply because most folks can't be bothered with anything more than spamming links. The proof is in all the irrelevant forum sig. links WF members spam with nonsense comments.

The chicken link in the SEW article (link in OP) is a good example of how to turn a hobby into a business, basically all they do is create a gathering place for anyone interested in chickens.

I have 3 sites that tap into an authority forums traffic (around 150k members). I posted quality content related to a sub-niche in that forum, enough free content they made me a forum Mod. (which has perks). I've been getting a steady flow of free traffic from that large forum for years, never missed a single day of traffic from that forum since my sites have been live.

Basically that large forum is a partner, I send them traffic, they send me traffic. Doesn't cost me a penny & the traffic is laser targeted to my sub-niche sites.

That meme almost made me spit my water on my computer screen.
