How does the Smart Shuffle work?

Update: The smart shuffle function has been replaced by Auto Shuffle. Pinterest requested that we do this as they don't want people shuffling their pins based on outbound urls.

The Auto Shuffle functionality shuffles your pins based on their title and description now so that similar topics are spread out in your schedule.

The shuffle function works like this:

If a user posts 10 posts which have a different outbound URLs like this:

AAABBBCCCC

Then the shuffler with mix them like this

ABCABCABCC

This spreads the posts out evenly.

But if you have many of the same posts like this:

AAABBBCCCCCCCCCCCCCCCCCCCC

Then after shuffling, you posts will look like this:

ABCABCCCCCCCCCCCCCCCCCCCCC

The shuffler mixes them as best it can but if it has too many of the same post, then those go to the end.

I suggest creating a few more posts with other outbound URLs if you would like more variety in between your existing posts.
