Michael Brill of San Francisco needed lemons.

He was going to pick up some 15-year-old sourdough starter that a neighbor had offered on Nextdoor, and he wanted to bring something in return.

Nextdoor, an app that connects users within the same neighborhood, is a natural platform for this practice. While people bartered on the app before the pandemic, some users are noticing a large increase of trade requests on the site…
