We will have a reputation system for users in the future. As to why you may want to contribute. If you use the website and you find value in it, you can always make it better not only for yourself but for others. Only here, not only can you add links and resources but you can also directly add features and new things as the entire code base is Open Source and thus anyone can edit/fork and make what they want with it for all other people to enjoy.
