Introducing the Test Track 4 Blog

This will probably get filled in more later, but Test Track 4 was officially incorporated on April 4th, 2026, and this is the first blog post on its own infrastructure (pds.at.tt4.net), thanks to Bluesky's AT Protocol.

We're all-in on AT at TT4, and as Permissioned Data makes its way into the specification, I'm looking many of my (Stuart P. Bentley, @stuartpb.com) prior application ideas that had out of steam in the past (usually at the agonizingly-monotonous backend implementation phase), such as Dingroll0, and finding that they would no longer prohibitively elaborate to implement.

I'm looking forward to what further experiments this platform will permit.
