I'm a long time Strava user, I have a four digit user id. Except for the year I won a free subscription for a year, I've always paid for the service. I'm a data nerd and cyclist.
This change in Strava's policy makes me very sad because it's clear they are managing it poorly and Strava might die as a result.
Who could step in to fill the void? Garmin? No, they're just terrible at anything other than collecting raw GPS data and it's clear they don't have athletes in mind when creating features. Even when they have winning products they find ways to sabotage them. Garmin Connect is full of potential, yet fails to engage users or become a social platform.
I kinda hope Veloviewer.com steps up to fill the void. It's all about data.
