That's like saying "If Coca Cola is really that good they wouldn't need to advertise"
Warrior Forum is the biggest Internet Marketing forum in the World. I think it would be dumb of marketers to not spend an hour a day reading or writing posts here.
And if you ARE a writer or a graphic designer.... You better spend a good 2 or 3 hours a day here.
For me, the more I read from people who post here, the more I trust to do business with. Of course I do my do diligence. I've paid people to write articles, design logos, design landing pages, etc... I have almost always had good results. And, of course, I had some really bad ones. (I'm sure just because you got a bad purchase at Walmart doesn't mean it's a bad store.).
On the other hand......
There are people who have been posting for years on this board who I know I would never trust. Just by clicking through their links and reading their posts you know they are full of ####.
My tip: Keep a list of the "good" people and "bad" people on this forum. It's up to you to decide which is which.
But, don't judge someone's success by whether they spend "too much time" on this forum. Sometimes successful people do like to give back. And sometimes successful people know what a value the Warrior Forum is.
