SharpReader

SharpReader is a rss feed reader. It's the best one out off all the other free ones. The new release just added one of the best things a blogger can have: A "BlogThis" plugin. It makes blogging a lot easier when you just press a button on whatever you find interesting and blogit.
It's missing a few essential features [make that just two], but it is under active development and getting better with each release. The keyboard shortcuts have also been finally implemented.

Keyboard shortcuts:

• F5 refresh current feed (like it was prior to 0.9.1.2)
• Shift-F5 refresh all feeds
• F6 focus subscriptions pane
• F7 focus item-headline pane
• F8 focus mini-browser
