I like how easy it is to create surveys, assign them to users/groups that are relevant as well as schedule their delivery at any time of day or night! Sometimes some questions in the survey take too long for my liking so have created a shorter version with only important information included which is great for those who prefer not to fill out lengthy questionnaires.
It would be nice if they could send reminders about surveys via email but this isn't an option yet either.
