Most people have the attention span of a gnat. No seriously, very seriously.

You will only captivate those idiots if you blog about sex and more sex or something similar...like food, but really you're better off with sex, only then will you have their undivided attention.
Anything else, bores them, or they suddenly lose concentration, or it's too difficult for them to absorb, to comprehend...
Sorry to tell you, you've had high expectations from your fellow men, keep that those expectations for your philosophy books.
As far as Real is concerned, give them what titillates them most - between their legs.
Short of that, good luck.
Mind you, you can always sex sugar coat it.
