I've had a premium Strava account for many years. I only use that one for our tandem rides, which are 90% of my outdoor riding, and 100% of my stoker's. I also have a free Strava account which I only use for my singles, maybe 10 posts to that account/year. I don't care that much about my numbers on my single, since outdoor rides on it don't figure into my year's training. I never upload anything except outdoor rides to Strava.
I like Strava fine. One problem I've noticed in the past couple weeks is that sometimes the file import function doesn't work. It gets the file, but then doesn't do anything with it. An irritation of using any group platform like Strava is that other people can change things you use regularly, like segment boundaries. If course I could just make some segments private.
