Below we've added a button for something called StumbleThru, which is powered by StumbleUpon and enables you to explore Mashable articles, rate them and get recommendations for content you might like. It makes reading Mashable a bit more serendipitous.
To get started, click on the Stumble button below. Once you see the StumbleUpon toolbar, you can "Like" an article, rate it or hit "Stumble" again for another article.
And, of course, StumbleUpon can recommend articles from other sites you might enjoy. In addition to exploring, you'll also see a "Stumble counter" on selected Mashable articles (like the one on the left) that tracks the number of times that post has been given a thumbs up. You can also follow Mashable on StumbleUpon, where we submit trending stories and editor's picks.
We hope you enjoy the feature. Let us know what you think.
