Wow, I like this quite a bit. Your tutorials are very informative without making me feel talked-down to.

How will you get users? I can imagine doing distribution via company training programs or via people telling their coworkers/friends about it (or maybe something else?). One of these vectors is going to be better than the others. Given your success on Reddit it's possibly a viral product, but if so, you need to worry about retention - it'll be interesting to see if users keep coming back to learn more.
