There are so many benefits to taking a breath and writing a well thought out message:
- Fewer notifications for everyone else
- It’s easier to link to your message/thought later
- It’s easier for others to respond (in a thread) to your message
- It’s easier to read because your thought wasn’t interrupted half way through by someone’s partial response

Tagging someone sends that person a notification. Its purpose is to get their attention.
If you’re just joking around or casually mentioning the person without needing something from them, it is okay to just type their name without tagging them.
