I just released my first Amazon Echo Skill, called "My Notebook".
You can use it to create notes in Evernote or OneNote using your Amazon Echo:
To try it out, say "Alexa, enable the My Notebook skill".
It was rejected twice (for good reasons) during the review process, and I learned a lot as a result, especially around keeping the conversation going, responding to help requests etc.
I'm caught between hoping it takes off, and people use it, but also hoping it isn't too popular, since it is free and I'm not keen on maxing out my credit card!
