I looked through your site so far, and I didn't see any math or any hands, which was discouraging. It's good to think about cognitive biases and how to reduce them, but really the way to make money at poker (especially at SNGs and especially at small/microstakes) is to understand starting hand ranges, position, tournament strategy, and postflop play as deeply as possible, and then learn how to apply those concepts to hands. You can't do that by thinking about theory, you need to actually look at specifics.

To be brutally honest, it's hard to see how you're going to differentiate your product from the hordes of poker blogs and forums that are already out there but have the advantage of having great poker players contributing.

Try looking at the book Small Stakes Holdem by Ed Miller. It's a good example of taking fundamental insights about how poker players play badly and using them to create an actionable strategy that says "play this hand, raise in this situation."
