The majority of the top 100 are web-based and free – great news for educators in an era of scant educational funding. New the list in 2009 are two of my favorites - Prezi (presentation software) and Wordle (word cloud generator). For ideas for on how I use these free web resources follow my links to Prezi | Wordle.
Note: The 2010 survey is being in progress. All learning professionals are encouraged to share their Top 10 tools to help build it further. Submit here. Kudos to Jane for conducting the survey. (And thanks to @russeltarr for his tweet pointing me to the survey.)
