+1 from me.
We're in distant parts on holiday and rode through a cafe in the middle of nowhere that had been stripped bare by riders earlier in the day. A long way from anywhere, so I had my suspicions and sure enough, Strava quickly revealed some of the culprits through the group.
Of course, I could have loaded up the AUK calendar on my phone, backdated the search, guessed the possible start points / distances required to hit that cafe and narrowed it down pretty quickly to a certain calendar ride, then searched on YACF for a topic associated with the ride, and worked out who rode based on counting the "I'm in" posts (minus the last minute "I'm out" posts). Or waited a month or two for the results to be published.
Is Strava a great solution for everyone? Of course not. Even setting aside the childish idea that people are now racing up hills because of Strava segments but before Strava, all cyclists went slowly and sedately and never attempted to ride fast (or compare their speed with others), there are plenty of reasons not to be interested in it. But pluralism is a great thing, especially when it comes at so little cost.
Thumbs up! (Or should I say, "kudos"!)
