WorkHack, a task list web app that takes simple to a whole new level. There are very nearly no features to WorkHack. There is no sign up, no tagging, no due dates, no multi-user support. Just to-do lists, organized into three priority categories (High, Medium, and Low) and sorted by color or size.To-do lists should be simple, or so claims
Getting started with WorkHack is easy: just plug in the captcha text on the main page and go. Tasks are added by entering them into the large textbox on your to-do list page, and assigning a priority level. Tasks are marked by color (red for High, orange for Medium, and green for Low) or, if you turn on the option, by size (the bigger the task, the more urgent). When you are finished with a task, click "Done" and it disappears from view (though you can turn on an option to make WorkHack display completed tasks, and re-add them with a single click).
You can reorder tasks via drag and drop, and save the current order (which WorkHack will revert to if you reload the page or toggle the visualize by size option). To return to a to-do list later you can bookmark it (or memorize the tasks group number, which is in the URL). WorkHack has RSS and XML options that allow you to export and take your data with you.
At first I was annoyed that WorkHack didn't let you edit tasks. But as they say in their FAQ, "It is ok if you misspelled a word or two; it is just a to-do list. Use the frustration to finish the misspelled tasks faster." And they have a point. To do lists should cause as little distraction as possible. Spending time fretting over making your to-do list perfect, or assigning convoluted priority scores and due dates and tags is counterproductive. Managing your list of tasks is never something that should be on your list of tasks.
