Sadly people were not clearer than this. I suspect some UI prettiness things, some ease of use things (onboarding) and a fair few misgivings (such as voice chat and how images work) that makes it feel user-unfriendly.
But I am speculating.
- I already learned Slack at my last 9 jobs
- I don't feel like blowing up my workflow and learning something new
- unless the value is overwhelmingly clear
if someone tried to switch my company to Zulip or anything else.
"what problem are you trying to solve?"
Basically, Zulip is the chat equivalent of a bidet.
The major reasons for us moving were:
* it is not Slack!
* lack of plugins from other applications
* inability to collaborate with external parties - customers, vendors etc
Unlimited guests is nice
But also you can actually pick up a conversation from a month ago, so is infinitely better.
