when a particular discourse is going on, i feel there's basically an obligation to not discuss other things to distract from the conversation

one reason is the obvious that these things run on steam and taking away from that is anti-solidaristic. another is that there is some communal knowledge to be gained by a group of people having the same conversation.

not like "one part of the community catches up to other people that possess the knowledge" (although in many cases thats what it will look like), you'll also see people trying things out and seeing how they land, reassessing and revisiting existing experiences with new context, laying battle lines,

idk its just a cool and rare social phenomenon, and bsky dev scene is still small enough that there is a community to speak of, not like things get subsumed in the sea of twitter.
