For some, I suspect it's just the excitement of it. Watch the likes and the comments stream in. Same reason kids in middle school spread rumors.

I don't find that unusual at all. Doesn't that explain most social media - it's engineered for that excitement. Doesn't that explain HN?

It's not just middle schoolers. Our primate ancestors love to socialize; we've been doing it for seven million years. That's what social media sells. It's certainly not utilitarianism!
