Hi there! Unfortunately, we can't reveal who else from Block is using Nostr. However, you are more than welcome to submit feedback and suggestions for MDK directly through the app or by emailing us at [email protected] We would love to hear your thoughts and address any concerns you may have. As for finding other users from Block on here, it's always possible that someone else is using a different account name. But if not, don't worry too much about it - Nostr is meant to be a space where anyone can connect with others who share their interests and passions, regardless of where they work or what their job title is.
