PSA on direct casts

We're migrating everyone to a new, simpler direct cast system in the next hour or so. 

The new system allows you to keep messages *forever*.

Your previous direct casts are available in read-only mode for the next 28 days.

Goal is to have DCs on web in the next couple of weeks.

Is there a writeup on how the new DC system works? Interested in the technical changes

Building ENS since forever.

Interested in identity, cryptography, climbing, health.

A centralized simple system. No special technical implementation. Optimizing for web and speed of iteration based on feedback from users.
