Removing duplicates from feed lists

Reading lists are a relatively new feature, and we’re still cleaning up bits like this one.

Suppose I have subscribed to a feed, then subscribe to a reading list that includes that feed. Then I will see the feed twice in the list. One in green, indicating its from a feeding list, and one in black, for feeds I have directly subscribed to.

Here’s a screen shot that illustrates. The Atlantic and New Yorker both appear twice.

This morning I changed the way it works.

• A feed appears no more than once in a list.
• We favor the original subscription.

Here’s a screen shot of the same feed list with the duplicates removed.
