I got started using Strava as a tool to find trails. There are plenty of apps for that today, but years ago there were not. When I was traveling to a new area I would search for strava segments in that area. I could easily differentiate mtb from road segments by looking for loops and/or zig zaggy red lines. At the time I had no interest in the data it captures. I just wanted to ride and had no interest in following others or seeing my lap times. As the Strava app improved I got more interested in it. The ability to add photos of my activity was a nice improvement. Now I use it not only for recording my rides, but also keep track of trail work. I save the workday as a workout and add photos to remind me what was done.
