I totally agree that this guide would be much more useful with each time a paragraph 'how can you help these people improve themselves'.
But I think that as it stands now most people would understand that these are just clichés. In fact, using this as a guide to look down on other people would be the behavior of an 'Agitator'.
One piece of feedback I really liked from this comment thread was providing some guidance on how to get better at reading someone else's code. I've made an issue out of that (code illiteracy) in a few blog posts before and I think that HN commenter is right.
I think I'd like to do a few posts on how to overcome some of these traits - beginning with reading code.
