Impersonal in the sense the article etc isn't being presented for the specific audience. It's just being dumped everywhere with the same contextual text ("Wrote this piece about...."). So, I'm seeing it everywhere in the exact same way. Which feels way spammy (and which I've admittedly had to do myself, as per the times). But, I'm used to feeling like the person I follow is posting stuff to the community in language specific to their readers. I say "used to", but I'm probably thinking back decades now. Back when your audience / reader base was the metric of personal. Not the platform.
