Quora has added SMS functionality using Twilio, which was implemented in a single night by one of its engineers, with the team spending time tweaking the interaction afterwards. The implementation used Quora's in-house web framework and Python, with a standalone web server built with Tornado to handle requests between Quora and Twilio. To get started with SMS integrations using Twilio, developers are advised to start simple and iterate on their design, building upon existing functionality to create a working product quickly.
