I would like to propose that we tighten up our question titles where possible. I know I've written some long, rambling titles, and I'm trying to go back and shorten them. It's not easy for me, but I think it's worth the effort. Here's why:
Here's how a question with a short title looks on Twitter in the ordinary timeline:
Here's what it looks like after I click "View summary":
When someone posts a cousin-bait title which has all of the details about the person being searched for -- name, place, date all crammed into the title -- and then the question begins with the exact same information, here's what happens.
In the SE summary, on Twitter, and probably most other places it is shared, it shows up with the exact same information in the title AND in the snippet which shows up in the preview.
For a comparison, here's what the example question looks like in a search result here:

My share, with the long question title:
And the auto-tweet, after the title was edited to be shorter:
With the new title, now people can see what the question is about.
