Twitter has a new product manager, the wake of a large re-org of the company announced this week. The changes will see Twitter dividing its business into groups including engineering, product, revenue product, design and research, and more, while also bringing on Kayvon Beykpour, the GM of video and former Periscope CEO, as product head. Beykpour will replaceEd Ho, vice president of product and engineering, as Ho steps down into a part-time role.
