In my experience, adding a reply can:
(a) add a new perspective to the chat, which often injects life into the conversation and keeps it from getting stale.
(b) articulate something that one of those already talking wanted to say, but couldn't manage to express.
We can't predict everyone's expectations about their threads, but on the whole I'd say it's a positive to leave a reply.
One caveat is that it helps a lot if we match the tone of their conversation in the reply i.e. if they're talking in short bursts of casual posts, it's better to do the same in one's own reply too, instead of adding long nuanced replies (and vice versa). That helps make it feel like less of a random intrusion.
@digital_carver this is good advice! Thanks so much it helps me a lot.
I'll try to add my bits more instead of just leaving stars. Thank you for this explanation! 🤗
