I don't have an online presence that links directly to my real life. I mean, no Twitter, no Facebook, etc. Forum usernames, Gmail address, etc. don't have any link to my real name.
So I guess I don't even have an online persona while I'm alive...
The only thing that comes up that is actually linked to me when you search my full name is a patent document, first item in the list. Quite proud of that, actually.
But I'm just a grumpy "old" man with a grudge against social media who's paranoid about data security, so...
