Join Corey and Sid as they discuss the newly announced Amazon Chime and Slack and partnership and what it means for virtual meetings, where the optimal place to host a video meeting between a user in New York City and a user in Taiwan is, how chat becomes exceptionally difficult when you’re trying to scale to hundreds of thousands of users, how the Amazon Chime team responds to user feedback, how Amazon’s own usage of Chime doubled in recent months and Chime scaled without a hitch, why the Chime team focused on and perfected the app’s plumbing first and how it’s now shifting its attention to polishing the porcelain, why the Chime interface displays a region label, what Sid thinks the number one misunderstanding about Chime is, and more.
