However, there is one thing that no WordPress.org plugin can do. Imagine a station where you frequently import posts from a feed (say, a livecam feed) into WordPress posts or pages, and you want all new posts in the feed to appear at the top of your index pages. For example, the plugin pulls a feed where 7 posts are currently active livecams, so you want them at the top of your main page, but they already exist on your site as old posts imported a week ago. So the plugin has to delete those old posts and re-import them as new ones with new descriptions/statuses and screenshots because they have most likely been updated recently.
The plugin in my signature allows you to do this.
