I used Strava early and hated it, every segment I rode I was DFL, and I thought it was pointless, so Imoved to Mytracks and used it for a long time because everything could be exported to a spreadsheet. Tried MMR once, but it said I was doing 99 MPH down a hill, so I decided the data would be inaccurate. Now I'm back to Strava, I have 2 KOM, a few top 5s, and seeing PR on routes I've ridden before is always a good motivator. At least 1/2 the people I ride with regularly use Strava, so it makes it easier to keep tabs and bragging rights.
