This morning we wrote about StumbleUpon’s site specific stumbling and Rafe Needleman’s idea of having a button on blogs that pulls up a random article. I pinged WordPress founder Matt Mullenweg (TechCrunch runs on WordPress) after the post and asked him if anyone has created a plugin for WordPress that does this. They hadn’t, so Matt wrote one and published it.
If StumbleUpon does decide to offer this functionality as a widget, we’d probably integrate it. The plugin Matt created doesn’t assign any value or ratings to posts. With StumbleUpon, it’s much more likely the random post would be interesting to the reader.
