If I look at the Glassdoor salaries for places I've worked the numbers (total comp especially, but also base salary) are sometimes quite low.

They get less accurate the higher up you go (where you also have less data points), I think mainly it's a combination of sparse data + older data points being way out of whack with recent increases due to the competitive market.

I've personally seen numbers at several places that some people on HN vehemently tell me I shouldn't believe... and sometimes, even Glassdoor seems to give numbers that a lot of commenters here don't always seem to believe (like that $268k number).
