The document introduces a new feature called the Nextdoor Speaker Series that aims to increase in-person interaction and user engagement on the Nextdoor platform. Research found that hosts would be willing to invite speakers to their homes if they were interested in the topic and speaker quality. However, hosts worried about not breaking even on costs if attendees did not show up. The solution was to change it to a crowdfunding model where guests could fund events in advance, minimizing risks for hosts. User feedback validated this approach helped create a more neighborly solution.
