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.

Instapaper is much bigger today than I could have predicted in 2008, and it has simply grown far beyond what one person can do. To really shine, it needs a full-time staff of at least a few people.

I don't even like being quoted in a press release.

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.

As long as I manage investments properly and don't spend recklessly, Tumblr has given my family a strong safety net and given me the freedom to work on whatever I want. And that's exactly what I plan to do.

Programmers work in bursts of productivity. Then, they let the brain rest and get back into it. A lot about the office world is not a great fit for me.
