Buffer, an app that stacks your tweets and publishes them at the best times for engagement, has just added Facebook to its repertoire. Now you can either schedule your Facebook posts using the default posting times (11am and 6pm) or just pick your own. What sets Buffer apart from the other tools is that with it, you can use the buffering pattern feature (paid only) to do post time-release posting instead of regular scheduling. This is not something you can do on other social media posting tools like HootSuite.
