This is an expansion of Matt Mullenweg's original Random Redirect plugin.
This is an expansion of Matt Mullenweg's original Random Redirect plugin which allowed you to create a link to link to yourblog.example.com/?random which would redirect the visitor to a random post or page on your website in a manner similar to StumbleUpon. Matt's original plugin also allowed you to limit the randomness to specific categories and post/page status.
We have taken the original plugin a step further, with Random Redirect 2 you can specify
random_keyword too, giving you fine grained control of the level of randomness. In addition to the extra parameters, you can also combine parameters!
