I have the App. Use it periodically. I am cautious about the start locations. I make them random and away a bit from actual start /end. I understand now that there is an auto randomizer.
I use it to document a ride for reference.
Problem with it is there is a subtle urge to "get that KOM", or top time for a "segment". I see too many Strava Slaves running signals, stop signs, very easy to fall into that.
Absolutely no social usage.
