Buffer Share Button
Buffer is an online content and social media sharing service that pioneered "scheduled sharing." Buffer users can add your page's content to their "Buffer Queue," which will then publish the content to their Facebook and Twitter feeds, along with your suggested or their amended comments... and it will publish those posts at times they have designated as most appropriate for their audience.
Add this button to your website or blog to let people share your content on Twitter and Facebook seamlessly. They can share right away or at a better time using Buffer's groundbreaking scheduling functionality.
Out of the box, this widget will automatically post with the page title, the page URL, and any representative page image that Buffer finds in your metatags. You can, however, override those defaults and create specific comments, URLs, images, and Twitter handle attribute from the widget flyout panel.
Regardless of the selections made, the final viewer will ALWAYS have the opportunity to change the content of the shared post. These are merely SUGGESTIONS that the owner of the website WOULD LIKE the viewer to share.
