Accessibility for non-technical users, and formatting.
In MatterMost (a very nice self-hosted Slack alternative) the integrated MarkDown-support means that sharing code and more extensive reports can be done with a helpful amount of formatting. I much rather read the ten lines of code a colleague is asking me about with code highlighting than without, and a summary of a colleague's visit to a customer reads a lot more pleasant with headings than without.
Also, emoji. Not something most of us on HN would miss, but a lot of the non-technical users seem to appreciate being able to nuance messages with them.
