Hacker News is _very_ full of over-confident people, believe me.
During a discussion of 'whether open source contributions were being overly important to job seekers' a while back, a surprising number of HN commenters automatically put themselves in the role of employer, peering dubiously over their glasses at me. Many of these commenters were hilariously under-qualified to be taking on that kind of role with respect to anyone.
I don't think SAT verbal is nearly as intensely focused on obscure vocab. I didn't do it, but did do a GRE verbal back in 1994 to get into grad school. For what it's worth, my score on this and my GRE verbal were quite consistent.
