Welcome, glad to have you. Here’s a few reasons why I think people join nostr.wine:

1. Access to filter.nostr.wine

2. Largest paid relay

3. Improved client performance (high speed relay that is geographically distributed + load balanced)

4. Improved discoverability (most people who don’t pay for write access still read from nostr.wine)

Let me know if you have any feedback or issues!
