Good stuff David, and almost all I’d agree with although I’ve no problem with people sharing a profile across platforms if the new one has different attributes. Let’s not forget MySpace came and went within 5 years, in social media the technology is leafs important the people are most important and really important you are active where your connected community are active.
I get the rant and know the people doing them, sadly their. 20th century manner is convincing people pushing not interacting and listening is the right thing to do.
They are bad role models for sure, but it’s not a bad thing to tell those who’ve opted in to what you say to find some new content and context to talk elsewhere.
