Except it’s often used in a way that goes beyond chitchat and bouncing ideas. I was pretty active in a programming community a few years ago, and then they decided to move official chat exclusively Discord which I disagree with on principle & was not going to create an account. Some (not all) decisions I would have previously expected to see on the forum got discussed and decided within Discord’s proprietary walls which cut some users out that previously were a part of the discussion.

It often happens unintentionally, and it poisons communities. Back when I was actively participating, and for a time even running our local Hackerspace, I insisted on a hard rule: our IRC channel is non-binding, anything of any relevance must be also discussed on the mailing group, and only decisions made on the mailing group are binding. This rule was keeping the community from going nova - shedding outer layers of occasional participants, and collapsing into a core group of friends that's in constant contact.

Even with that rule in place, when I graduated and had to focus more on my work, I realized I'm slowly becoming an outsider to my own community, simply because I'm not able to keep up with the torrent of random conversations on IRC. Back then, there were no LLMs available to summarize the 1000+ messages people sent between 09:00 and 17:00. And even if they were, it wouldn't have helped, because the problem was, people who wrote those messages were bonding together, becoming closer-knit every day, while I was becoming more distant just by missing out on this.

It's what eventually made me stop participating - and from what I talked to other people in and around our Hackerspace at the time, I'm not the only one. Which is why I say, chat groups are, by very nature, poisonous to communities - including off-line ones. They need careful managing.
