I certainly agree, and use a lack of social media presence as a positive signal for hiring.
However, it was a bit of a battle to convince the other stakeholders in the company that it should be viewed positively instead of negatively. And this is at a security company, where we have a whole open-source intelligence department!
I think you and I are in the vast, vast minority.
Oh, you won’t waste a bunch of time “cultivating your network” or whatever? You won’t advertise to phishers how our company is laid out? You aren’t addicted to yet another social network? All pros.
