There’s no shortage of online task managers – but that doesn’t stop more from popping up all the time. Two relatively new (and free) entrants might be worth your while if you’re looking for a new app in this category.
Goal Organiser tries to move you from task management to goal management. In addition to entering steps (tasks), you also tag each one as to the goal it will contribute to. Coupled with other information about tasks, the application tries to automatically suggest your next action at any given point.
Listaculous, meanwhile, is all about simple lists of tasks. You can have as many lists as you want, with tasks that can be reordered and highlighted with color. Their twist is that you can access your lists through their site, through a Google gadget, or on any other site that embeds their control.
