    Always been a little skeptical about Stumbleupon ads. The bounce rate from their ads tends to be in the high 90′s, no matter what kind of content you have. Most people who do go to StumbleUpon go to get a little nugget of information, a quick little snippet that they can take a look at and that’s that. No long term engagement at all, and I’m not even sure how popular StumbleUpon is for most marketers these days.
