FeedMyTwitter is a twitter auto posting application that helps you predefine what twitter updates you want to be fed into your timeline.

You can send automatic tweets based on categories such as movie quotes, funny messages etc. You can also specify RSS feeds the way you do with twitterfeed for updating your blog RSS feed on twitter.

If you happen to make a story or some other smart marketing for your product on twitter you can have custom messages updated randomly to your twitter timeline.

Once you login to the site, you can start or stop the service anytime. You get to specify the time interval after which random tweets need to be posted.
