The cool folks from the Eurosky team just brought you a new site:
eurosky.tech
, portal to the Atmosphere. I'd say it's the crispest explanation so far of what the Atmosphere brings: 1. one account 2. that works with a bunch of apps, and 3. your data from all apps is yours, portable, interoperable.

Today, we’re excited to introduce Attie, currently as an invite-only closed beta. Attie is the first agentic social app on atproto. It’s something completely new — an experiment in making building on the protocol more accessible.

If you run into any bugs with Attie feel free to tag me about it, we've tested it internally for a bit but letting all sorts of new people use a thing inevitably turns stuff up.
