Audrey Watters at Hack Education has given her Top 10 Ed-Tech Trends of 2011. My favorites are the pairs which are in conflict:
Khan Academy (6) versus The Higher Education Bubble (8)
Open (9) versus The Business of Ed-Tech (10)
I'll side with Khan and Open. Indeed it seems that in any world with cognitive surplus, education should become easier, cheaper, and more common. That's what my sidebar is all about.
