That hope is very difficult to achieve. VRChat has limited data that it can handle.
A realistic method is to obtain data via RSS. It is possible to subscribe to RSS within VRChat. There's even a service that allows us to obtain Nostr posts via RSS! Using this, it might be possible to make this a reality to some extent.
It would be very interesting to subscribe to and display specific hashtags.
I'm interested not only in VRChat, but also in Cluster and Resonite!
