It’s funny. I find “Here’s How” as irritating as anyone but I don't associate it with LinkedIn but with the other socials like Twitter and Instagram (often associated with “a thread…”)
I do get very triggered by people who are thrilled/delighted/excited/humbled to be doing something.
I don't mind if they show me, rather than tell me.
If they have to tell you something, it's probably not true. (although I don't have a lot of direct experience of thrilled, delighted, excited, or err humbled.)
No probs, that's easy: Thrilled, excited and delighted, are basically the same thing - look at me. Social media humbled is "I've just met a disabled person".
