It’s a typical design problem: it can’t be heavy and light and big and small. Neither decision will satisfy everyone all the time or cover every edge case: if Apple implemented Mute in Ihnatko’s preferred way, millions of people would be just as irritated when their scheduled alarms didn’t wake them up.

There’s plenty of prior evidence that design can come late to a company and still succeed, of course; there’s less evidence that design can come late to a platform and still win over that platform’s whole ecosystem.

In a sector where financial resources are relatively low, effective prototyping fills the innovation gap, reducing the risk of innovation practice and solving the problem of the innovation funding calls, which ask for detailed project proposals but often do not provide the guidance or tools needed to come up with the good idea that makes a great proposal.

I’ve know lots of people who got into services thinking that they can use the income from clients to bankroll their own product ideas. That is not an impossible scenario — it’s been done before more than a few times, and it’s a beautiful thing when it happens. But it’s very, very difficult to pull off. To do services, you need to wake up in the morning with a different approach to life from the way you wake up in the morning to do products, and only a few people have the skill — and stamina — to juggle both at once.

Shouldn’t everything be obvious? Unless you’re making a product that just does one thing – like a paperclip, for example – everything won’t be obvious. You have to make tough calls about what needs to be obvious, what should be easy, and what should be possible.

Features don’t matter. Products don’t matter. Outcomes matter. People matter. How does your product benefit the people? What’s the outcome of using your product?

What does "craft" mean for designers who work exclusively on problems of services, software, or organizational change and political influence? And how can schools change their foundational focus without abandoning the obvious rigor of traditional craft-based learning?

And speaking of booze, how come there's a field for declaring I'm an alcoholic (opensocial.Enum.Drinker.HEAVILY) but no way to tell people I smoke pot? Why are the only genders male and female? Have the people who designed this protocol really never made the twenty mile drive to San Francisco?
