If you use Keynote for your sermon presentations, you can post tweets of your main points (or any other information) automatically while you preach with keynotetweet. Simply add text inside the tags [twitter] and [/twitter] in the presenter notes section of a slide and when that slide comes up in the presentation the script will grab that text and send it to Twitter on your behalf.
When you first launch keynotetweet you can add #hashtags to be added to all your Keynote tweets or select none. Your account information must be in your keychain to access your account, but that’s it. The script handles the rest.
Tweet Scriptures or main points, anything you want. This is another way to use Twitter to help spread spiritual ideas and thoughts and preach to larger audiences. You can download the Applescript here.
Preach on Twitter while you preach from the pulpit!
