Boring surveys

I have said lots of good things about online surveys but like anything theres some to look out for i don't often do the 30 minute surveys as i have a full time job and surveys are just something i do in my spare time i just attempted to do a 30 minute survey at youropinion.com that turned out to be longer than 30 minutes it was long and tedious and worth a lot more than $3
i would much prefer to do multiple short surveys than the longer 30 minute ones.
That's my opinion though i say that i have done long surveys with valued opinions and deemed the payments fair.
kind regards D.W.Hogg.
