just wanted to let you know about some great writing I just found. It will tell you what your main questions should be when implementing gamification. What I find very interesting and most important is
Focus the Scope of Rewards
[…] Context is vital to gamification — consider rewarding activities in narrowly scoped areas to give developers something concrete and achievable to strive for.
Before you implement your gamification system, think carefully about how it will scale and take future needs into account.
Thx @Engaming for sharing another cool article!
