I haven't looked into ditto yet. When you say don't connect nostr clients to ditto, what is the client to use? 

 DItto is a nice nostr relay that can filter out Spam plus the Soapbox Web UI. Soapbox was ported over from  the Fediverse. It was used by Gab, Spinster.xyz, and TruthSocial.  

 So use soapbox web ui connected to ditto relay?  

 Yes, Ditto will serve the Soapbox Web UI for you.  

 Do nostr clients like Amethyst not work with ditto? 

 They work fine. All you have to do is add the relay to your relay lists and you start showing up on at least the global feeds of, whatever ditto relays you add. 

 Ok so this is a bit like the outcome of nip42 AUTH and isolating a relay

Do notes broadcast beyond ditto relay if user does not isolate their relays just to the ditto relay? 

 In a sense, I definitely agree with you, but I'm definitely trying to keep this to a region-specific relay. More of an experiment than anything else. Someone who's comfortable with nostr and selecting their own relays can just add the relay to their normal list if they want to participate and post there and show up in global. If they really feel like it, they can get the Nip-05 and show up in the feed. 

Also the idea behind this was kind of to set it up for Meetups in my area, so maybe somebody in Oregon could discover meetups in their area, that they didn't know about if they're already on nostr. 

It definitely silos somebody to that relay only if they sign up through Ditto, but nothing is stopping them from taking their keys and importing it into another client. 

 Good luck, You will be competing with MeetMe, Neighbors, Facebook and more =) 

 True facts, but hopefully the folks who are already going to Bitcoin meetups will take an interest in this. I had a couple people from surrounding areas come to one of our meetups and say they would be interested in using something like this, so I spun it up for people to fuck with.
