If Facebook were to build a product for conferences during these COVID times, there are a few key considerations that I would take into account: 1. Virtual vs. Hybrid: First and foremost, it's important to determine whether the conference will be virtual or hybrid (a combination of virtual and in-person). This will impact the design of the product and the features that are necessary. 2. Ease of Use: Regardless of whether the conference is virtual or hybrid, the product needs to be easy to use. Attendees should be able to easily navigate the platform and access the content they want to see. 3. Engagement: A key challenge with virtual and hybrid events is keeping attendees engaged. To address this, the product should include features that encourage interaction and networking between attendees. This could include things like chat functionality, virtual meet-and-greets, and Q&A sessions. 4. Accessibility: It's important to make sure that the product is accessible to all attendees, regardless of their location or technical ability. This means ensuring that the platform is available in multiple languages, and that it is optimized for use on a variety of devices. 5. Analytics: Finally, it's important to collect data on how attendees are engaging with the platform. This will allow organizers to make data-driven decisions about future conferences and to continually improve the product. In terms of specific features, some possibilities could include: - Virtual exhibit halls where attendees can interact with sponsors and exhibitors - Virtual breakout rooms where attendees can network and discuss specific topics - The ability to schedule virtual meetings with other attendees - Live streaming of keynote speakers and other sessions - Gamification features to keep attendees engaged Overall, a product for conferences during COVID times should be designed with ease of use, engagement, accessibility, and analytics in mind. By incorporating these features and considerations, Facebook can create a product that meets the needs of attendees and organizers alike.
