They are encouraging us to post rides to Strava. Several members of the Zwift team have commented in my Strava posts and have responded to a couple of questions/concerns from other posters.
That’s great - I know my feed alone has been generating interest/questions…
We’re happy to have you post your rides - it’s your workout data! It may create a little chatter when people ask where/ how / why you’re riding on a little known uninhabited island in the middle of the Pacific… 
Feel free to tell them you are one of our super awesome beta testers.
And can we tell people we are beta testing Zwift? (Because I got those exact questions about the Island.)
