Twilio is pretty great. I used it for https://github.com/Ell/catfacts and it was super easy to setup and get going. Had to take the site down due to lack of funds but processing SMS messages and sending them was a breeze.
I did not but thats pretty neat. Twilio api is really fun and I had a lot of fun using it in my django app, good to see other python project code using it too
Using twilio, we implemented SMS package delivery confirmation (via UPS) and our customers love it.
So easy even my grandma could do it.
That should be our new tag line :)
This is a feature that could be done with Twitter too, yes?
