Speaking of changes in paid internet services, Instapaper’s new owner has started charging for premium subscriptions again. When they were acquired by Pinterest, they discontinued premium subscriptions and made all features available for free. But the new owner needs to make some money off the service, so they’ve re-instituted Instapaper Premium. I went ahead and signed up for it, at $30/year. As with Flickr Pro, I don’t mind paying for a service, if it means I don’t have to put up with ads or spam or having my data sold off, and if it means that the service has a sustainable business model that will keep it from going under.
