_Tudubot is a public to-do list that you manage by tweeting at it. How does it work?
See it in action in the following thread:

It was built with Node.js, PostgreSQL, and the Twitter API. It took two days to hack together. It runs on Heroku's free tier. And all the code is here. Contributions are welcome, including from first-time contributors and junior devs.
Special thanks to Omar Sinan and his article How to build a simple Twitter bot in 17 lines of code for getting me started.
Any questions? Let me know in the comments. I'm happy to share what I've learned.
