From Jakub Szwacz:
Sputnik is a RSS reader for your desktop or laptop computer.
No installation needed, just download it, unzip and start using. No registration, no login, no yet another password to remember. Keyboard (and mouse) shortcuts allows for convenient and fast browsing through articles.
When you launch the app see what's behind this icon. All articles are stored on your computer, so you don't need internet connection to read them later.
You can tag any article with any tag you like.
Very convenient for organized people. The app keeps all data on your own computer, and only there. No servers somewhere in the internet involved.
