I like your extensions. It's interesting to consider where everyone's personal "wall" is: the stage at which they have trouble going beyond. Many people, for example, are passive consumers who can barely use systems (Level 1), let alone monitor them (Level 2). (If that seems harsh to you, remember that you're on Hacker News, a highly non-representative sample of the population.) I work in R&D, and so I spend a lot of time designing things (Level 7) and improving on existing products and concepts (Level 6-ish). I even like to think I'm good at it, some days. But I rarely have good, new ideas of my own (Level 8), and I don't think I've ever had an actionable one: certainly, I've never had an idea or plan worth founding a startup over, or worth quitting my job to become an author. It's surprising how wide the chasm separating those two levels seems, at least for me.
