Users can choose which streams they follow; think of them as separate mailing (sub)lists if it helps. E.g. for our own automated-reasoning-oriented Zulip (<a href="https://sneeuwbal.zulipchat.com" class="">https://sneeuwbal.zulipchat.com</a>), we have a stream called "shameless (but AR-related) announcements". So far we're not on any spammer's radar, though, so the announcements are pretty relevant.<div class=""><br class=""></div><div class="">It's really a glorified chat.<br class=""><div class=""><br class=""></div><div class="">Jasmin</div><div class=""><br class=""></div></div></body></html>
