Marco Arment, the CTO at Tumblr, has been working a personal project for a while that you might know about. I’ve been using Instapaper on and off for a couple months, but I never seem to remember why I go on streaks of abstinence. The service is the best method I’ve found for storing links and reading them across multiple devices.

Arment is officially taking Instapaper from a personal hobby to a startup. Arment has 800,000 users registered to his service, with 200,000 regular users. Arment is self-financing the startup by himself.

“It’s all self-funded so far and has been for the first six months of the service. My only costs are my time, server fees and paying the contractor for some Web work.”

As for the future of the product, Arment is looking at developing an HTML5 version that could be supported across all mobile platforms into the future.
