A neat new tool for companies that are looking to use Twitter for marketing: Twittertise, which lets you schedule Twitter messages in advance to send automatically.

What’s the point? Twitter is a live wire, so whatever you send now is immediate. That works for individual users, or

companies trying to take part in real-time conversations. But if a company wants to send out pre-written tweets — like promotional messages, coupon links, reminders, etc. — over the span of a day or a week, they’d need someone to remember to manually send out the messages. (Or some sort of home-brewed scheduling system.)

Enter Twittertise: A simple Web site that you can log into with your Twitter username and password, type in tweets — 140 characters, max — and schedule them to send at a specific time. Want to send people to a Web page? Twittertise routes links through a URL shortening tool called Bit.ly, which lets you track how many people have clicked through your link.   Read more on Alleyinsider….
