I received this as a comment few days ago and I think that it is better if published here...
A group of researchers at University of Nevada, Las Vegas, are investigating effects of Weblogs on “Social Capital”. Therefore, they have designed an online survey. By participating in this survey you will help researches in “Management Information Systems” and “Sociology”. You must be at least 18 years old to participate in this survey. It will take 5 to 12 minutes of your time.
Your participation is greatly appreciated. You will find the survey at the following link. http://faculty.unlv.edu/rtorkzadeh/survey
This group has already done another study on Weblogs effects on “Social Interactions” and “Trust”. To obtain a copy of the previous study brief report of findings you can email Reza Vaezi at email@example.com.
