When I'm out and about there's often times when I want to remember something for later; maybe it's a good idea I've had, or a reminder to download a song that I've just heard, or a reminder that someone's birthday is coming up and I need to do something about it. I usually do this by calling myself and leaving myself a voice mail message. But this takes a while.

You can now do the same thing using Twitter which is way quicker. You set up an account for a Twitter notebook at http://www.mytwitternotebook.com/About. You can then send tweets directly to your notebook. You can then go to the notebook site and see/manage all of the notes you've sent to yourself. This is a great way to remember things, it's quick and and easy.
