As everyone on here spends most of their time reading anyway, might as well recommend a book:
"Switch - How to change things when change is hard" by Chip and Dan Heath
I became aware of it a while ago when reading this
article (unrelated to Bitcoin) and immediately saw how it could be applied to what Bitcoin is dealing with right now.
I recommend reading at least the first chapter of it which can be found here: http://www.heathbrothers.com/switch/
Also, with regard to the ongoing arguments on the development team it offers a new angle for motivating behavioral change and effectively setting people on a course when you don't have the authority to do so.
"What looks like a people problem is often a situation problem."
This book could be inspirational to everyone who seeks to promote the acceptance of Bitcoin.
I'd actually like to hear if anybody here has read it or whether you think some of its suggestions can be put to practical use here. I might have to dig it out of the pile once more.
