Unfortunately it's worse than that now. It used to be that everything got siloed into channels, now things get siloed into the new forum system.

These forum channels don't automatically appear in the sidebar and you get no indication of anything new added unless you specifically follow the thread.

Moving into forum threads is a great way to kill a conversation, perfect even, honestly I wouldn't be surprised if the feature was added just so Discord could appear in "forum" searches. There's no way the feature was planned when it's so bad for conversations.

In any case the discord mod quirk of stomping on discussion inertia plus this horrible new forum system guarantees a conversation fizzles out immediately.
