Buffer

Buffer is the best way to share great content to Twitter, Facebook and LinkedIn from anywhere on the web, with just one click.The Buffer Chrome extension allows you to schedule content to Buffer (https://buffer.com)
By using this tool, you will be able to visit different websites and schedule to Buffer directly from those other sites. This allows you to post the articles in front of you directly to social media, or to your social media queue for future scheduling.

The Buffer Chrome extension integrates directly into various websites and allow you to share content more easily. You could enable the integration for facebook.com, twitter.com, and tweetdeck.twitter.com, to name a few. A nifty "Share image" button also will appear to help your share images throughout the web more fluidly. Any of these integrations can be disabled via the extension's settings page.
