The Gamification of the interfaces around us is starting to become common place. But this amazingly simple technique can go so wrong.
Gamification is not just throwing a badge, leaderboard and a few levels onto an app. It's about planning context and strategy. Getting it right is an art.
The seed book for is month is Gamification by Design By Gabe Zichermann, it's available on O'reilly, Amazon (in kindle format), and Book Depository.
There is also a good realistic talk on Gamification at UX Australia 2011.
And there is a book website too - Gamificationu
