Zwift is actually the greatest thing that has ever happend to a sports enthusiast. It’s just absolutely cool to be totally independent on weather. I know, i know you basically could ride outside whenever you wanted as well but when its freezing cold, stormy, rainy, icy, 3am in the morning or you feel the need to do a workout you can always startup Zwift. It has changed a lot. It’s Great, keep up the expansion and the great work 
Cheers
