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?

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.

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.

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.

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

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