Attention to detail can't be (and never is) added later. It's an entire development philosophy, methodology, and culture.

One reason I love the Kindle, more so than the iPad, is that on the Kindle you can't do anything else but read. It's the best, because it does the least. It doesn't even show a clock.

With a Web and iPhone app, I try to find new and tiny ways to delight my customers. They may not notice, but it helps drive goodwill and makes your product remarkable.

Making a product better often requires removing features.

I've worked with many large and small publishers, and nearly all of them love the value that Instapaper provides to their readers.

Emphasizing and rewarding length over quality results in worse writing and more reader abandonment.

Instapaper wouldn't be of as much value if it weren't for these mobile and e-reader devices. They give you a separate physical context for reading.
