Howdy lawrencewu, I think it's fantastic that you're working on something to scratch your own itch! It's exactly what I did a year ago when I started work on http://www.memorific.com http://www.memorific.com to build a SRS that was fine-tuned for software developers. We just changed to public beta a few weeks ago and started generating revenue and it's been a great experience helping people learn, grow, and meet their goals for learning. Keep up the good work on noot.io and have a blast doing it! There's nothing like making a product that people use and enjoy.
