Tweeto is a to-do list of sorts that integrates with you browser to help you organize and manage your tasks. To begin with, sign up for a free account and create your first to-do list. You can move items around with Tweeto's drag-and-drop ordering system. You can also tag and highlight particular items for emphasis, and later on you can go by this color coding and tagging system to filter results when you search your list. Take advantage of Tweeto's "smart tagging" system for quicker labeling; it automatically tags tasks for you with keywords you use regularly. You don't need to be online to use Tweeto, since it's an AJAX-based app, and it works for all popular browsers and platforms. When you're done creating your list, you can share it with your friends and contacts via email, and you can even delegate certain tasks, since Tweeto is open for collaboration.
