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.

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.

Writing your own blog platform is like roasting your own coffee: it's impractical and you probably shouldn't do it, but for people who really, truly care about it, it's worthwhile to them for their own personal priorities that sound crazy to everyone else.

I don't need every customer. I'm primarily in the business of selling a product for money. How much effort do I really want to devote to satisfying people who are unable or extremely unlikely to pay for anything?

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.

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