You must have noticed the change in your profile and other friends' profiles.
Here's how it works: For the first 5,000 posts, you'll get your very first medal. For the next 5,000 posts (10,000), you'll get your second medal.
The third medal goes to those who'll reach 20,000 posts.
Fourth medal = 30,000 posts
After 100K posts, the next medal will be awarded every after 20,000 posts.
Total number of medals = 16 (for 200,000 posts)
Those who will accumulate 7 medals will get a HABAGAT or High Sierra back pack as a prize.
