ToTheZeroth News is a relatively new light-weight cloud-hosted feed reader service (RSS and Atom). It operates on a freemium basis (a small subscription fee is mandatory only if you want to track more than four feeds). It's not designed to compete directly with services such as Feedly or NewsBlur, but rather cater to people who want short summaries in their Firefox sidebar (or in their smartphones). Until now, the service has only accepted USD, but now bitcoin has been added as a payment option. To encourage payment in bitcoin, great conversion rates are offered: currently 0.6 mBTC/$ (in normal units, that's well over 1600 USD/BTC).

Disclosure: As should be obvious from my user name, this is self-advertised. Still a relevant announcement, I think.
