Feed Pauser is a cool little plugin from Keith Dsouza which lets you delay the publishing of your posts to your RSS feed. Posts can be delayed by a set number of minutes, hours, days, weeks or months.
Posts can also be completely hidden from the RSS feed but hiding them through the post editor.
Feed Pauser was originally developed to allow bloggers to double check their posts before they went out to their subscribers. I’m sure many of you will find it useful :)
