“..teaching is the “killer app” for a newer, more ethical approach to marketing. Those who teach stand the best chance of getting people to become passionate.

* Makes a request. It asks you to “Play with me”. This is why you are compelled to touch it.

* Is fantastically straightforward. The design suggests, “When you pick me up, it’s going to be clear what’s going on.” This is why great toys never have manuals.

“PIDA is different from other IDEs in that it will use the tools you already have available [vim, etc.] rather than attempting to reinvent each one.

“..if I were launching a new website, here’s what I’d do. Instead of hiding the Feedback link in the upper right hand corner, I’d place a form right on the main page. A big form. And I’d bend over backwards to get people to use it.

“Getting a reply increases satisfaction along four dimensions. It increases current benefit, it increases expected future benefit, it creates a common bond with the individuals who posted replies, and it increases identification with the group as a whole.
