I have not been around for too long, and although I have been reading and learning about internet marketing for about two years now (as well as becoming a Marketing With Alex student around two months ago), I can speak from a beginner's perspective.
Forums, like this one, although extremely helpful, generally lead to one thing for beginners: information overload.
When people start in internet marketing, having a clear focus is very important. For instance, right now, my focus lies with driving traffic to my blog. More specifically, I am focusing on commenting on other blogs and posting in forums. However, when interacting on this forum, I see SO many different ideas and methods, not only for "making money online", but even for driving traffic to websites (my current focus). This information isabout the methods I am using now, but I also read about article marketing, syndication, social media (twitter, facebook, linkedin, and now even Pinterest...), social bookmarking, backlinking, SEO, and many other methods/tactics.
All these different ideas and methods can be extremely overwhelming for a beginner. I think that is the reason why many people fail online. They do not have a clear focus, so they do not stick to one idea until they start seeing profits. They jump from idea to idea, or even try to do everything at once. They jump off the deep end. And, forums are not helping them.
And, don't get me wrong, I LOVE WarriorForum. I have learned so much from here. However, I have felt the sting of information overload, as I am sure many of my fellow beginner marketers have.
