This plugin will allow all authors to have their own tweets shown on in the widget area of their posts, by adding it to their profiles. 
That way any multi-author blog can let their bloggers promote their own twitter account and not a joint account.

A Author based twitter widget, made to help multi author blogs have individual twitter widgets for their authors.

Most people who run a multi-author blog need to tell their writers what post they should write. And so administrators send emails with a URL of the post source, the keyword for the post, any notes accompanying that. And sometimes a user notices a post that is worth writing and he wants to tell the other writers, so they have to email the administrator who will tell the other users and everyone will kill themselves in the end. The Posts To-Do List plugin allows you to get rid of that rigmarole.
By a convenient box in the posts editing page, everyone will be able to share the posts they think are worth writing. You have this little box, where you put the URL of the page where you read that great post, and the plugin will fetch the title by itself. You will then be able to change the retrieved title, suggest a keyword and add other notes, set a priority and assign the post to some user of the blog. And if you want to leave everything blank but the title field, leaving a suggestion that anyone can catch and deepen… well, you can!
No more emails to tell “You do this and that, use this keyword and don’t forget that…”. Everything can be down inside WordPress. Not only by the administrator, but by any logged in user.
You, as the administrator, want everything in the power of your hand? No problem, you can decide what user roles can add new posts to the to-do list and what user roles can delete already added items. You want your users to stick to the post you assigned to them? You can hide the posts you have assigned to other users from their view. From a simple stats page it will be immediately clear how many posts you have already assigned and how many of them are still to do, so that it will be easy to understand how much your writers have done and how many posts you have still to assign. Almost every action is powered by AJAX, so that no page reloads are needed and you do not even notice it is happening, it just works.
