Found this neat free app for sharing on social media. The problem with propagating stories is that you have to have a good stock of them lined up and be able to schedule them at the right time otherwise the effect is somewhat lost. Bufferapp is able to stock up a 'buffer' of stories you find whenever you are browsing throughout the day and then publish them at your specified times.
Optimal tweets per day? See this article. Just add them to the buffer, set the times you want and you're off.
Link in multiple accounts or Facebook pages that you manage. Very good so far.
