Some people do, and panic a bit if the measurement is "a dash", or even "to taste".

I'm not one of them, but I do weigh ingredients for a different reason. Example, I want my two-pound bag of frozen whatever to last seven days, because I only shop once a week. So, I weigh out 1/7 each day. I'll leave it to others to decide if this is more, or less weird.

It's a handy guideline, especially for beginners.

It's oddly satisfying even if you don't follow it to the gram. I barely use recipes but why not.
