Gathering some compliments for morale and to maybe put them on the site somewhere:

• this is the best interactive app I have used so far. I use w3schools and other apps but this is by far the best interactive I can find right now. Thanks so very much for making this.
• The simple explanation of the basics is impressive, especially in mentioning little things that I often forget aren't a given when teaching. Well done!
• Dude, this is brilliant! I love it! I am past some of the stuff in here and I'm just going along to see how you do it and I feel like it would have been such an easy way to learn I'm almost upset I didn't have it when I did.
• I've just finished the Tic-Tac-Toe project. Futurecoder was the best interactive (or non-interactive) programming tutorial I've ever encountered. Great pace, perfect UI/UX. I come from Javascript/Java/PHP, so Python feels quite weird especially because of the whole "pass by reference" thing, but I'd love to dive in even more.
• I like this way, way better than codeacademy where at CA, it’s a lot of reading instead of action. The topics and subjects are broken down into small digestivable pieces (step by step) where you are 99% active learning while doing the exercises, compiling in real time. More classes need to be taught this way! I love it!
