I estimate that I use it about 3 times per day, 15 times per week, around 750 per year. That's 1,500 plastic spoons saved since I started. And since I now have my own silverware, plate and cloth napkin at work, I have eliminated plastic forks, knives and paper napkins that I would have used at meetings and parties.
What little things do you do that add up (and maybe even inspire others)?
I think it would be a good idea to invent a travel mug designed to hold a companion spoon - like those canisters that come with their own scoop on the side.
