Welcome to Tech News Briefing. It's Wednesday, January 3rd. I'm Alex Oscela for the Wall Street Journal.

On today's show, if you scroll through social media over the holidays, you might have seen a

flurry of year-end reflections and engagement announcements.

But in general, have you noticed that your friends are just posting a lot less? Turns out they are and that's a problem for social media
