Visit this site if you’re going away on vacation next week and the thought of not posting a single tweet while you’re away makes you feel uneasy. TwitDrip is a new service that will surely stop all your worrying. It basically lets you schedule tweets for any time in the future. You can have a tweet posted every day at 8 PM for the next 2 weeks, and give your followers the impression that you’re just taking things calmly, not that you’ve taken a break from it all. And if you have lots of tweets written already, you can also set a “drip” for your tweets, and have them posted at the frequency you want.
And a service like TwitDrip is also going to be useful if you’re an Internet marketer. A service such as this one lets you have promotional tweets delivered right on schedule. TwitDrip makes it dead-easy to market any product of yours, without having to get near a computer more than once or twice a week
TwitDrip is a free service, and you can also use it without having to sign up for an account first. You can sign in to the service using your Twitter username and password here.
