Crystal's Google Calendar to Twitter
For this to work efficiently you will want to create a calendar in Google Calendar specifically for this Applet. I say what the post is in the main title of the event along with #tweet. Under Where I put the picture URL to be shared with the Tweet. Under Description I put the Tweet. It helps to create the Tweet on Twitter before creating the event so you can keep track of characters being used. To repeat a tweet daily at a certain time you just repeat the event in the calendar.
