It's a private silo with no public indexing by search. Makes it terrible for technical topics fine for a chat platform.
It's a bad hybrid of chat and forum. None of the advantages of rich forum posts and typically too may participants for it to be easy to follow. Noticeable if you are not in the main timezone as the others.
Discord has threads and topics, but these features are a bolted on afterthought instead of core functionality so it just doesn't work as well

It's not that they are hard to navigate necessarily, it's that for a technical based community where topics can be very long lived an instant chat platform isn't really a good solution.
Where instant chat is transient, forums bridge the gap between a wiki and asynchronous chat making it better suited for the task. Throw in external indexing and information becomes far more discoverable.
