Show a random post on every page load.
The Random Post on Refresh plugin allows you to randomly display a different post on every page load.
Using this plugin is simple:
[random_post_on_refresh]
Automatically redirect to your latest, oldest, random, or other post through a custom URL
This simple plugin is a widget that displays a list of random posts on your sidebar. You can exclude certain posts by ID.
The main advantage of this widget is random movement of random links and every time they are changing.
