I get that, but the context from the article is that of an interviewee looking up the interviewer and commenting that the interviewer was a "ghost" online. To me, that's somewhat bizarre. What bearing does your interviewer's hobbies have on your perception of whether the company and the role would be a good fit for you?
Where I live, it's expected from candidates to show they looked up the company and have prepared a question regarding a project the company is working on or something else about the company itself. So, you actually end up googling the thing.
