Zulip looks great, but it also looks like the sort of thing I'd have trouble convincing everyone to switch over to because even though it might be more useful in the long term, in the short term its a bit more complicated (even though we're on the free slack, so we're looking to move elsewhere)
That's exactly how I'd explain it. It took me about 3 hours to be extremely comfortable using it and feeling productive. But first impressions by all of my coworkers were "It's so confusing", "There's no way we can use this, it's terrible", etc. But it's amazing. Just absolutely fantastic.
