I hate gamification of... Everything, but if it's just "oh hey I've been here for X years and at some point I got 5000 upvotes / 800 downvotes, that's cool I guess", I'm kinda for it actually.
It's like with videogame achievements. They're not super important for most people, but sometimes it's nice to look back at the stuff you've played or what you had to overcome. Some are addicted to it too. Real life doesn't give you much satisfaction in this way.
