I'm in the middle of reading the 'original scroll' of Jack Kerouac's 'On The Road', and brilliant it is too, in it's raw, unedited glory. Fast, visceral, discursive and with a healthily ad hoc approach to punctuation.
The edition I'm reading also includes a few essays on the publication process which offer some great insight into Kerouac's approach and beliefs, and this quote leapt out as a great distillation of the need for all communications to be interesting, not just right, relevant or vetted-by-research:
"People aren't interested in facts but in ejaculations" (journal entry, December 1949)
I guess it's a precursor to Howard Gossage's line that the consumer only reads what interests them, but this quote really makes the concept pop (sorry).
