Remember The Milk, the personal task management tool, is now integrated with Twitter.
By adding RTM as your friend on Twitter, you can add tasks to your Remember The Milk account directly through the microblogging tool as a direct message. You can also have reminders sent to you through Twitter. This same system works for sending tasks to other friends on Twitter, so you can keep them in line too. Remember The Milk already has integration options for your iCal and your cell phone. Adding Twitter to the mix just helps centralize and align its service with one that is already used by so many other people and start-ups.
Imified has also created a way for you to integrate your Remember The Milk account with AIM, and Retweet offers a suite of Twitter bots to make your life that much easier.
