Instapaper is a bookmarking service that allows web content to be saved so it can be "read later" on a different device, such as an e-reader, smartphone, or tablet.
I'm a free user but if I read more I'd pay. Instapaper keeps things simple, they're not trying to recommend more content or upsell you on something. The browser extension is easy to use, I save something from twitter or a co-worker shared and I read it on my phone.
