About a week ago I found out about the service Jott. What's neat about Jott?
Jott is a revolutionary new service that automatically converts your voice into e-mail and text messages—anytime, anywhere, with any cell phone. Jott makes you more productive and efficient by capturing your ideas, notes to self, tasks, and more without using your keypad.www.jott.com
With "Jott Links" you can even post to WordPress, Blogger, Typepad, LiveJournal, and Twitter from Jott.
I've tested this with both my Twitter and WordPress test blog. Works really well. I even found a way to post from Jott to Remember The Milk via Twitter.
