I don't use Mastodon, couldn't find meaningful signal for me there (same for Bluesky and Threads). 

But just added my account on Openvive to try it out. The idea of surfing Nostr, Mastodon, Bluesky and Threads from the same app is really interesting. https://image.nostr.build/c704640c9e2a651333f41e44cabe4d47009e384f7601ef21cb96c98eb629505e.jpg 

 Interesting. I'll have a look. Whats your Mastodon?
