I leave it up to you to find out which task is the most captive and front of mind, and which one is the most voluntary (hey! I can't spoil my results just yet!).
If you are a practitioner, a consultant or working for a web analytics firm and your job includes some web reporting and analysis, please fill out the survey.
If you are blogging about web analytics, I would be grateful if you could spread the word about this research and help me get more survey results.
