I believe the Attention Trust equation of
How I Browse + What I Say + What I Read = Me
ignores an important factor - the 'Bullshit Factor'
How I Browse + What I Say + What I Read * (Who I am trying to impress) = Me
I might casually leave a philosophy tome from Wittgenstein out on the coffee table to impress visitors but that doesn't mean I'm going to read it.
Ever insightful, Monty Python had this to say on the issue
I drink, therefore I am.
