I'm no expert, and I only was able to browse for a couple minutes, but here's my 2 cents. If I understand correctly, you'd like to charge money for courses about how to start a business, or do other things that people in their 20s need. This comes at the same time the entire education model is being flipped upside-down by free MOOCs. I can tell you are aiming for a higher-class niche of high-quality content, but in the end, I think this kind of thing will be unsustainable. Maybe I'm wrong, and there's some verticals that can support paid content or you can stay better than the free stuff, but it seems like a longshot. That said, the site looks great!
