iOS/Android/Firefox/Chrome/Safari: Previously mentioned social feed reader Feedly unveiled a new version that allows you to roll Tumblr account and all of the blogs you follow into your RSS feeds and other social news the app provides. Then, you can +1 and share stories on Google+ right from the app, in addition to Facebook and Twitter.
Feedly is available as a browser extension and a mobile app, and once signed in you can pair the app with your Google Reader account and Tumblr account. The app also serves up additional news from curated channels like "DIY" and "technology" that the developers think you'll enjoy, and arranges it in a clean, minimalistic interface.
The latest updates allow you to use Feedly as a Tumblr client, and lets you reblog, like and comment on posts from other Tumblr blogs you subscribe to without leaving the app. Additionally, the Google+ integration lets you +1 or post directly to Google+ with the URL to the story right from inside the app -- similar to the way the service already works with Facebook and Twitter.
Feedly 6.0 is completely free and available now.
