Zulip founder here; I'm curious why you think that? Here's our thinking. Topics within a stream are ordered by the time of the most recent message. We keep the complete history, both of messages and topics, because it's useful for search and following up on things. Personally, I regularly reply to a conversation whose last message was a month or more ago to follow up with new information (often after getting there fr…
Hi there! I just started using Zulip (first-time user) looking forward to migrate off Slack and unfortunately I've been really disappointed. In Slack I can just load the website and begin typing into whatever channel I'm at (or use 1 click to select the right one if it's not the current one). In Zulip, it seems there's been a deliberately goal of explicitly designing it to be excruciating painful. For some reason Ent…
In Slack, most messages are a single line, and are very real-time. E.g. if a channel is getting 100 messages a day, and a conversation starts in the morning, you're not going to try to engage with that conversation even that afternoon.
In Zulip, communication is asynchronous by default. This has a lot of secondary implications; e.g. it means that by default you can assume people will see your message, rather than just the people that check in the next few hours. This means you can have substantive discussions on the platform, and the medium correspondingly encourages more multi-line, thoughtful posts. So we've currently decided that having to type an extra letter to compose is worth the tradeoff.
As an example, not having compose open by default allows us to use single letter keyboard shortcuts for navigation.
In any case,

* Private Messages (called DMs in Slack) in Zulip work the same way they do in Slack, with an open-by-default compose box.
