Community daily streaks + Levels

Similar to the Bible app or Snapchat, having daily streaks is an incentive for people to engage with the community daily. This could limit inactive users and even go a step further depending on what is required to continue to streak: i.e. logging in, posting, commenting, etc.

Membership levels are another great incentive- less subtle as it's something other members should be able to see as an encouragement to 'level up'.
