No vote, because I don't typically vote unless something sticks out.

I thought the article was pretty ok. I liked reading your story of personal development. :) The short sections with clearly labelled points were effective. I don't have too much objection to the specific advice you mentioned, except: there were certain ones that apply to, yes, a nice large portion of people, but an individual might find that they are more compatible with people outside that portion (eg. people who appreciate math jokes as flirtation) and I think it's worth looking for that compatibility even if it's not as common.
