I've taken a lot of surveys over the years (for fun, as a hobby, as something to do as a stay-home parent, for money), but I've never had one beg me to pass it along (they're usually invitation only). So here, take this survey!
Take me! I'm a survey! The one was actually interesting and ran along the lines of politics, social networking, and your opinions concerning issues that affect our country and the world. It should take you 15 minutes or less.
In their words:
"A primary objective of this research is to understand how people communicate with friends, family, colleagues, etc. about the issues most important to them. To that end, we are interested in gathering information from people within your own network of friends and family who you think would be interested in providing feedback...The information provided by you and your invitees will go far in helping us understand the dynamics of your social network and how you communicate within that network."
