Google Co-op is about sharing expertise. You can contribute your expertise and benefit when others do the same. Help other users find information more easily by creating "subscribed links" for your services and labeling webpages around the topics you know best.

This is a work in progress, but even in its early stages, Google Co-op has the potential to let you contribute your expertise to the overall goal of making information more discoverable for everyone.
