Avtually, STU delivers nothing but a bounce traffic... I am having a lot of visitors from STU but they are useless and don't even stay my site for more than 30 seconds... waste of bandwidth..
From what I`ve seen myself StumbleUpon visitors aren`t serious buyers. As you say, they have a quick look, which gets you traffic, but is all rather pointless if they spend just a few seconds on the site.
