I would love to meet some ATProto dorks in real life, and I think we would have fun. I also think there is a relatively large concentration of us in New York City.
I am thinking a simple get together. We could do it outdoors somewhere that is reasonable and easy to access (central or prospect park) or could pick an establishment that has a nice large garden area and book a large party. I am indifferent to the implementation, I just want to garner sufficient interest. If 3 more people will show up I will make it official and set the date for July 26th. That gives us time to share this around and let it flow through people's circles.
Who should come?
Anyone who has an account on an ATProto service is considered an enthusiast. The bar is so low you could trip over it.
