Random Redirect is a cool little plugin that sends the reader to a random post on your web site. As the author describes it, it’s like StumbleUpon for your website.
Although I doubt I would use the plugin on any of my sites (it just doesn’t feel like a good fit), this seems like a really interesting way to expose new readers to old content. I know I’ve “rolled the dice” a few times on Generation X Finance. Give it a go yourself!
