A lot of people sometimes find themselves very busy. We get overwhelmed with assignments, projects, deadlines and other mayhem, and at times, a to-do list can really help with managing all those tasks.

Luckily for you, many new and feature-rich online to-do lists can make doing the many tasks you need to do a little more manageable.

When looking through these services, all of them had features that included sharing tasks/lists by email and subscribing via RSS to a feed of your tasks.

Now, let’s get started at looking at a few of the most common Web 2.0 oriented online to-do lists, along with who can possibly use them and some ideas on how to use them:

Remember The Milk

Remember The Milk is an easy-to-use, yet feature-rich and Ajax loaded online to-do list which allows for access from multiple devices, including the Apple iPhone/iPod Touch and integration with Google Calendar and Gmail. It allows for features like tagging your tasks, prioritizing your tasks with different colors and you can also create different to-do lists.

Remember The Milk also allows for emailing tasks to your account, twittering tasks to RTM, viewing your tasks in a Gmail Labs addon, iGoogle gadget, iCal feed or Google Calendar gadget and the ability to add several options to each one of your tasks including completion time, date due and more.

It also supports another helpful feature when you’re not online – offline access with Google Gears. For $25 a year, an RTM Pro Account adds Windows Mobile, Blackberry and iPhone/iPod touch support as well as priority email support and access to their beta-testing program.

Remember The Milk is my personal favorite for to-do lists because of its ease of use and flexibility, and I would recommend it for managing any kind of personal tasks.

Voo2do

Another site that has a lot of Ajax loaded into it is Voo2Do, which seems more broader than just managing simple tasks. It has many of the features Remember The Milk does, and also offers some advanced time tracking capabilities to track time left and time spent on projects that other todo list managers might not have.

Voo2Do, just like Remember The Milk, offers a developer API and each one also offers the ability to see projects that you’ve marked completed.

Voo2do defines itself from other online todo lists because of its more advanced time management features, including a built-in timer (shown by the play/pause buttons in the screenshot above) to track time spent on tasks and would make a great todo list for a worker looking to log hours or use professionally.

Todoist

Todoist is another online task manager which prides itself on simplicity. Todoist has a simple, but intricate interface (that confused me slightly at first) that breaks down tasks under projects (categories). Todoist did take a little getting used to, but after learning where all of the settings were underlaid on the main page (below) it was quite helpful.

You can set todo items, sub-items and even sub-sub items to organize even the most complicated tasks and tag/label each one to your liking.  It also has plugins/addons for iGoogle, Netvibes, QuickSilver, Launchy and OS X Dashboard as well as Gmail integration and a Firefox sidebar.

With most of the standard features that other list managers have, Todoist would be a great application for somebody looking for a software that is more flexible than anything, but still offers most standard list features. It also has a $3 a month premium service that offers SSL security, reminders and a more advanced labeling system.

Ta-Da List

Ta-Da List is a multi-functional to-do list that has a relatively simple user interface compared to Remember The Milk and has browser support for the Apple iPhone.

Ta-da List prides itself on being the web’s easiest to-do list, is more centered around the idea of creating multiple lists for just about everything and also has simple features for sharing your lists. Ta-da Lists are great for a user who is looking for simplicity, and just needs some basic features to manage a couple (or more) tasks.

Bla-bla List

Bla-bla List is another to-do list which operates all off a small Adobe flash window. Bla-bla List also brands themselves as “Lists without any blah blah!” and it sure is – the lists are indeed simple and easy to use like Ta-Da lists and again allow for other common features like sharing lists.

I could see Bla-bla list being used again, like Ta-Da Lists, for somebody who needs simple features, in a simle interface that’s easy to use.

Do you often rely on online to-do lists instead of a piece of paper to keep track of what you need to do? Let us know in the comments what online to-do lists you use and how/what you use them for!
