@instagibbs This is invaluable feedback!  It's exactly the kind of confusion we want to clear up.  I've made several edits (not pushed yet) based on your suggestions, but one thing you said confuses me:

> OP_0 is used frequently, but it has a different meaning than OP_2 (one pushes 0x00, one pushes 0x50+0x02).

According to the [wiki docs](https://en.bitcoin.it/wiki/Script#Reserved_words) 0x50 is a reserved word.  Can you clarify for me what exactly OP_2 pushes?
