Google updated their Maps app for the Android platform. The changelog is pretty basic:
Improved battery performance for Latitude and Location History users.

But I noticed something new. Maybe, it was added earlier but this screen came up for me for the first time today when I checked-in.
This leaderboard shows that you get points for every check-in and you can measure your ‘performance’ against all your contacts in your Google Circles.
Your check-ins are still visible to only those users whom you shared with.
