Quuu

If you use Buffer to queue up content to go to your Twitter or Facebook, you probably know the power of that. You probably also know the terror when your Buffer queue runs dry and the river of content becomes barren. Quuu is a godsend if you queue up content to your Buffer, because their service automatically adds curated articles to your Buffer for you. Choose from a few different categories relevant to your audience, set it and forget it. Brilliant.
