wow this is by Miguel Grinberg who is the author of some of the best Flask tutorials and books around. Nice to see Twilio is attracting such high quality writers for their blog
I nearly wrote an article for Twilio but didn't complete the process. But have written similar posts e.g. [0] and work with other writers who also do this form of instructional technical writing. Would love to chat sometime if you have time - contact info in my profile
