Facebook is continually looking for ways to help you share more stuff. Today, the social network announced a tool for developers that will help you easily share quotes from an article. Rather than having to copy and paste a snippet of text across apps, you'll be able to simply highlight the words you want to share and post them to Facebook with a click. In the News Feed, the post will appear as a block quote with a link to the original URL or source. And yes, you can add an additional comment on top of the selected text.
