Sell yourself, sell your work

an important question is why indeed do people that do cool work dont write or talk about it or worse (to them) sell it and advertise it.

i also motivate myself to browse deeper (or visit obscure second hand dusty (book)shops) to find such unspoken of things.

Why don't marathon runners go to a local toastmasters to talk about their run? Probably because if you are doing one you ain't doing the other!
