I probably should have put this in the recent survey but the idea came to me after completing it. I saw in the survey Zwift floated the idea of a $25 a month subscription fee. As a infrequent user and with the crap Australian exchange rate that means I would be paying $35AU for a service which I might not use for 3 weeks. Not overly appealing let me say.
As a suggestion, what about the ability to buy blocks of say 100 - 500k? That way infrequent users like myself can still ride when we need to and Zwift will still make money (which they absolutely deserve to). This would provide users with a great deal flexibility and may actually attract a lot users who would not normally fork out for the monthly subscription, so this may prove beneficial to Zwift as well.
Just putting it out there as an idea
