**This Website is Hosted on Bluesky**

This weekend I found myself digging through the AT Protocol specifications and the Bluesky Personal Data Server (PDS) implementation. In doing so, I discovered that I could setup a website that is fully hosted on Bluesky.

When someone with ADHD doesn’t respond, there are several reasons why:

1. We didn’t see it, our inboxes are often a mess.

2. We have forgotten.

3. We know we have to respond but have a difficult time connecting the dots to make it happen. This sends us into a cycle of shame.
