Waste of time.
In keeping with other messages posted, I too experienced problems with the surveys. Getting one or more a day, I was constantly "bounced". Either I didn't qualify, or, the survey was full. Having been bounced from the original survey, there was usually an option presented to find another survey... A survey would be found, however, after your first input to the "survey" there would invariably be a "technical error", so you get bounced out of that one as well. Given the level of personal information I gave, suitable surveys should/could have been found. Valuedopinions might like to take a look at the plethora of "technical errors" I was getting as well.
