I find myself to be mostly in the 3rd column, and sometimes in the fourth. This just gave me some specifics of what to focus on. What columns are you people at?
Give me a couple more years and I'll be at four pretty solidly, though I think I'll focus my learning myself rather than focusing too heavily on this guys assumptions of what I should learn.
Guess I need to brush up on my data structures and learn some Erlang.
I do like the reading list included had some books I'll defiantly check out.
