Cammy Bean's typically thorough summary of a session by Brett Schlenker has lots in it that's useful. 

Given my focus on learner engagement, I was particularly taken by this list:

• Keep it quick
• Make it short
• Be really creative
• Make something that actually affects behavior (marketers want people to change their behavior – drink pepsi not coke, drink coke not pepsi)
• Make it truly memorable

Don’t just need IDs on your staff – get some creatives in there who look at things a bit differently.

Understand gaming theory and gaming design. 

Put the customer/consumer/learner first.  We say we do…but we don’t often do it.

I reckon the really tough one here is "be really creative". I'm not convinced that a lot of people in e-learning are particularly interested in creativity. Indeed I reckon many (most?) are fearful that the conditions necessary to stimulate creativity (lack of structure, "not knowing", playing not planning etc. etc.) will lead to loss of business. Indeed, the phrase "Don't just need IDs on your staff - get some creatives..." is particularly damning - isn't it!?

For me - and for many long-term learning designers - the act of designing a learning experience is deeply creative. It's why I do what I do.
