I love the survey modules - what handy fillers and information givers they are. Usually you'll find a survey or two on this site because they engage your visitors and if you ask the right questions, for your view audience, people are happy to give their opinion.
And they add visual and dynamics to your site too.
The core survey module is quite cool. It can be configured to fit into tiny spaces, be public or private with a date set to expire.
For a core addition to a website, this is a very funky module.
Use it!! You'll love it.
