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.

People will pay for something they like because they want to ensure its future.

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.

Making a product better often requires removing features.

Keep building and supporting new tools, technologies, and platforms to empower independence, interoperability, and web property ownership.

People want to download publications quickly and read them without cruft. Publications that started in print carry too much baggage and usually have awful apps. 'The Magazine' was designed from the start to be streamlined, natively digital, and respectful of readers' time and attention.

If you sit on, sleep on, stare at, or touch something for more than an hour a day, spend whatever it takes to get the best.

I started out from a pretty modest background, so I always had a pretty good sense of money. I always had to work for my money, save my own money, I always bought my own stuff with my money... trying not to waste money unnecessarily.

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

With Betaworks' drive and resources now behind it, I'm confident that Instapaper has a very bright future. I'm looking forward to seeing what they can do.

Instapaper does support paywall sites. I have a list of them, that when someone saves something it sends a copy of the page as they are viewing it only to them. If you subscribe to a paid site, you can save the content. I'm not really touching the money.

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.

Apple already had everyone's billing information from iTunes... you could buy things just by typing in your password... That, for the first time, brought very, very easy payment to the modern software world. That, more than anything, is why there is a business for paid apps.

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

Microsoft loves losing money with online services, so this should stay free forever... unless they get a new CEO who isn't crazy about pouring billions into a hole.
