I generally look at three quantitative data points:
- The leaderboard for the last period.
- The userboard for the last period, sorted by posts, likes, and visits.
- Their profiles, to understand in which area they are contributing the most.
And three qualitative aspects:
- Type of posts: Are they questions? Are they answers?
- Quality of posts: Are they short comments? Are they valuable contributions?
- Mood of the posts: Are they sharp or understanding? Do they align with your culture or go against it?
