I've come across people mentioning Toastmasters online at least 3 dozen times in separate contexts over the years. Yet no one IRL knows what the hell it is or where to find one. How can something be so commonplace here and completely alien outside of online spaces. I've never been to one or had the word toastmasters ever mentioned in person before. Is this like an alcoholics anonymous, but for public speaking?
