A couples' reading list.
Step 1: My wife and I both download an app.
Step 2: We link our accounts.
Step 3: We each find and read articles in the app, Pocket-style.
When done with an article, swipe right if I think my wife should read it. Swipe left if I don't want to pass it on.
Step 4: Open the queue of articles that my wife thinks I should read. Read them. Swipe right if I want to chat about it with her. Swipe left if I don't.
Step 5: On the weekends, as we're going for our walk, talk about the articles we both found intellectually stimulating.
