I love the concept, but I don't know if 5 years is even enough time for people to have gotten over current events. If you made it 20+ years, I suspect that would work better.
20 years! Frankly hadn't thought of going back even further. But I guess if Lindy holds true, the farther you go back, the better it should get. In such a case having options to filter would be helpful, as other commenter suggested.
In any case, good luck, and I hope I'm wrong. :-)
