@pmroman @Greengordon @Mastodon Their own bio.
If someone's bio says something like "head of software engineering", it's probably not a good idea to try to "explain" something like git to them - they will 100% already know and it comes off as patronising.
Same if you try to "educate" someone on a topic like law, but actually they're already a lawyer, so your legal 101 is not helpful.
That's all it's about.
