I was really impressed with what I learned. Qualtrics has hundreds of question types, you can embed different media into your survey, and you can do some very clever tabulation of responses to different questions to spot patterns and trends as they emerge. And the best part is that the computer programme does most of the statistics work, leaving you free to analyse and act on the results.
Every member of my institution has access to Qualtrics during a trial period; I'm definitely going to explore it fully. With more functionality, and the ability to customise more fully, than SurveyMonkey, this is definitely something worth investigating.
