Yes, actually. MH 370 and Ukraine are two stories that began in March of last year. They're still relevant today.
The news is a collection of stories. The big ones last a long time. If you want to sound like an informed world citizen, you should keep up on the big stories. It's not always easy to tell which stories will be big, but if you start following them early, it's easy to keep up with them.
Ukraine is still ongoing, and obviously relevant. At what point should someone have started following the story? Does it have to maintain relevance for a minimum time period before it's worthy of following?
