Projects
Community Notes (fka Birdwatch) lets people add helpful notes to tweets that may be misleading, and uses a technique called matrix factorization to determine which notes are helpful or not. The project takes into account the perspectives of raters who have rated notes similarly or differently in the past to rank the notes that are most widely helpful to create a better-informed world.
Periscope was a one-with-many live video streaming app created to "see the world through someone else's eyes." Through an in-house developed low-latency HLS protocol and pub/sub system, one could hold a real-time conversation with the world.
Side Projects
