Twerbose tours itself as a site where you can be more verbose in your message by using their service to post longer tweets. They have a feature list on their site:
* Post massive tweets easily
* Comment on other people’s massive tweets
* Optional advanced wysiwyg editing
* Add Youtube videos to your tweet
* Control tweet privacy
* iPhone friendly!
You must provide your Twitter username and password to use the service. However! I did like their terms of service found here. They will remove tweets and/or block your IP address for nudity, hatred, or just constant blatant product promotion. The idea is to expand Twitter into more than a microblog service when you have more to say.
