As the web gets more commercial, more companies want to track and know the real you. The backlash against this — and the desire to have “ephemeral” interactions in the digital world — is why Andrew Busey, the creator of iChat 19 years ago, has built Banter, a chat app with no names and little storage. The app lets people sign up with any user name and discuss … well, anything they want.

Update: It’s important to note that the iChat name was purchased by Apple from Andrew Busey, but he did not build Apple’s iChat app. Jens Alfke built iChat at Apple.
