Would a simple app allowing ethereum users to PM each other be useful?

This would be a website where you can send a private message to another ethereum address, and you can read your messages by having MetaMask open – only you could read your messages. Maybe have a public chatroom as well that also displays each users address/balance just for the hell of it. Messages would be stored in a regular database rather than a smart contract so it's instant and no fees. There must be projects like this already (Status?) and I am just wondering if others would like a service like this, as I'm wondering about developing it myself.
