I tried to write autoposting tool but always face with oauth interface problems. Does anybody has programming experience with oauth?
You can use 'tweetdeck', most powerful free twitter software. If you have blogger blog or wordpress then they would post automatically to your twitter profile.
Hootsuite does allow scheduling of posts. It's free. But the followed links are framed with a hootsuite header. You can also schedule blog posts and then use twitterfeed to send the rss feed as tweets to twitter. (Wprobot has the free clickbank module) Lots of fun options when you combine it with a blog.
FutureTweets.com is a free service that lets you schedule your Twitter messages. Send it at a specific time in the future or send a reoccuring Tweet daily, weekly, monthly or yearly! But, I think it is a web based module. I did not try it yet.
