This is an exciting new plugin (only available to WordPress.org users, sorry) I found while following my friends on Twitter. It randomly and automatically publishes old posts at specified intervals on Twitter, which will help promote your posts to a wider audience by giving them the extra exposure they deserve!
Go to http://wordpress.org/extend/plugins/, search for ‘Tweet Old Post’ and it will be the first on offer:
Download it onto your computer and upload it into your FTP browser such as FileZilla. Alternatively go to your plugin page and request ‘Tweet Old Post’ and upload it to your plugins.
Once it’s installed, don’t forget to activate it…
…and click on ‘Settings’:
Fill in the fields to set up what you would like to happen, and don’t forget to confirm by clicking on the buttons at the bottom, to save your settings and to send a ‘practise’ tweet:
Here it is shown in TweetDeck – isn’t it exciting? Now your old posts will get a better chance of being read by a larger amount of people in different time zones throughout the Twittersphere!
