Part of effective organization and task management is integrating the Tasks data into tools you already use.
A calendar view of your upcoming tasks is a very valuable view. In particular, it can help you with your scheduling and planning.
Having a separate calendar for your tasks is nice, but it is even better to integrate it with your other calendars so you can see how everything fits together. This is what iCalendars are for.
RSS and other XML syndication formats are really wonderful tools; many people think the are the 'next big thing'.
You can use the RSS feed to monitor progress on your tasks, especially if a few different people are using Tasks with you.
If you already use iCalendars and RSS feeds, Tasks integrates nicely with your existing tools. If you don't, give them a try - you may discover some wonderful new tools.
