Wow amazing post, did not have a chance to read yet but this is definitely "print worthy" material. What I mean by that is when I run across really good posts, I print them so I can read on paper outside etc.
Anyway, I did a skim and found this excerpt:
"You should write about information."
And can really relate to that. I've been blogging for about 7 years now, mostly failing but the last year I've had a few big "hits" even one here on HN.
Almost every one of my blogging successes were data driven. What I mean by success is they went viral on their own without any artificial boosting other than basic sharing with my followers.
