There is a trophy system where you earn trophies for actions you take. Liking a post, making a certain number of posts, doing something for the first time etc etc. Again just a bit of fun. I haven't added any or changed any from the default. I will probably add more in the future, but they probably wont lead to any real life rewards You can view your trophy count on your profile page
There's a few things I really wished I had gotten a trophy for when I was "doing them for the first time" just saying!
