I guess it depends on what you’re looking for. I don’t go on Twitter to see people talking about Twitter. I don’t go on the fedi to see people talking about the fedi.
If you want to engage with people about the platform I think you’re inherently limiting yourself.
Also. Damus has a Twitter account….theres tons of other accounts dedicated to nostr on other platforms…not sure what your point was with that. (Actually I do. I’m just giving you the benefit of the doubt)
