I get it for things you do on the side to broaden your horizon, but how often do you actually need to Google things for your day job?

Idk, of the top of my head, I can't even remember the last time exactly. It's definitely >6 month ago.

Maybe that's the reason some people are so enthusiastic about it? They just didn't really know the tools they're using yet. Which is normal I guess, everyone starts at some point.
