I don't know if it's a good thing or a bad thing that I had the courage(?) to click an xoxohth link at work.

I think people are going to be averse to having their minute-by-minute activity mined for any purpose, so I don't see that as a recruiting angle. What I do think is that there's more signal in a person's willingness to learn later in life rather than at age 20 when it's expected. I'm more impressed by the 37-year-old who picked up a machine learning course or textbook on his own and, in a year, picked up a respectable working knowledge of it. Whether he went to college is immaterial, at that point.
