The effectiveness of StumbleUpon can be greatly over represented by raw traffic. For example, I added HP:MOR. At the time of this comment, it has received 6704 views, but only 59 thumb ups (of which two are myself and MikeBlume). Stumblers will leave a site quickly for the next Stumble, if it doesn’t grab their attention.
(Though I do consider it worthwhile to have introduced the fan fic to 57 people who liked it enough to give the thumbs up.)
