i think it was really cool that you had a working demo of the first lesson right on the main page! I did `dd` and `i hello world!` and already started to feel invested even though I am an emacs user and don't really have a desire to learn vim. I think it's because you get a quick dopamine hit from doing those lessons and also gives you a good idea of how the site might work.

I almost wish that first lesson could have just kept going for a while without having to signup or anything. Maybe after you hit like 10 or 20 lessons, or when it starts getting more involved you could then ask for them to sign up / pay.

Either way, nice work!
