It’s a hot day and the weekend. Time for a couple of random StumbleUpon traffic tips.
If your website is mentioned in a high-quality article on another website or blog, why not thumbs up that article?
High quality is important here. You could just thumbs up anyone who mentions you—but if the article isn’t interesting, stumbling it probably won’t provide a traffic benefit.

However, if you can submit the miscategorized page to StumbleUpon advertising for approval under the new category, and they’ll change the category to the one you specified once approved (I’ve seen it take 30 minutes, also seen it take four days).
