Retention, interest, usage, and awareness ratio over time.
Technologies with less than 10% awareness not included. Each ratio is defined as follows:
- Retention: would use again / (would use again + would not use again)
- Interest: want to learn / (want to learn + not interested)
- Usage: (would use again + would not use again) / total
- Awareness: (total - never heard) / total

This chart splits positive (“want to learn”, “would use again”) vs negative (“not interested”, “would not use again”) experiences on both sides of a central axis.
