Plume and Twitlonger
When you type a tweet which is longer than 140 characters, Plume
automatically propose you to use Twitlonger to post your
Twitlonger will automatically cut your tweet, add "(cont) and add a link to see the complete tweet.
When you receive tweets, Plume automatically request Twitlonger
to display the messages with their original length.
However, it might happen that the request fail and that the real tweet (with the link and (cont) characters) are displayed.
