This article describes what Answers Network is.

The Yahoo! Answers Network lets you connect to people whose knowledge you trust, in the topics you care about. It's a network of contacts, made up of Answers users who are fans of other Answers users and have added them to their Contacts list.

By connecting to existing Answers users and inviting non-Answers users to join your network, it's easier to tap into all their knowledge. By adding contacts to your Answers Network, you can keep a network of knowledge advisors at your fingertips.
