Basically, a plugin for WordPress creates a PHP function (called a filter or an action) which is triggered when a particular event (called a hook) occurs. When several filters are supposed to be triggered by the same hook, you can define their priority.

When you're writing a plugin and you're facing unexpected behavior, it may be a priority issue : some internal function, or a function from another plugin you had forgotten about, is running before your own and processing the same bits you're trying to pass through your function.

Wouldn't it be cool if you could easily list all filters and action for every hook, in their priority and execution order ? Would be cool. Well, it is cool actually : get your hands on WordPress Hooks and Filters Flow.

    What I want to do on my blog, is every few hours take the oldest post and move it to the
    front of the queue, all automatically. Anyone know if there is a plugin that can do this or
    a simple way to set up another plugin to do this (use my own feed perhaps)?
