Switchboard allows the SOL community to push any form of data on-chain. The protocol can be used in many ways such as determining the current price of an asset for collateralized lending, determining the state of a tracking number to auto settle funds on arrival, and determining the current standings of fantasy sports rankings.  Switchboard is also permissionless. From a developer's perspective, you can build and manage your own data feeds, all of which can be done from Switchboard's Publisher.
