Leaderboards are designed to answer the question, What (and Who) is hot right now? Leaderboards are more worried about "What have you done for me lately" than "What's your all-time reputation/contribution."

Here are the actions that increase the content engagement score (from most valuable to least valuable):

• A Comment
• A Like (Facebook or Network)
• Any kind of Share

At its core, that's it — other factors come into play, such as a member's behavior. For example, if the member has already commented on several other posts, or commented on the same post several times, his/her comments will not be as valuable that day.
