Almost every major tech company in the Bay Area uses Java in some respect: Google, Amazon, Facebook, EBay, Netflix, Yahoo, LinkedIn (almost entirely Java), and Square just to name a few. It's not discussed that much because it's not "cool" or "cutting edge", which frankly is how languages should be in my opinion.

I work at LinkedIn, we actually do use skills in a number of places (like the job pages); typically they are used more of a "here's how your skills compare to other people's" and less of a "you'll get hired if you have skill X listed". We know people can game them, so we try to only use their skills in ways that would be helpful if their skills are actually real to give less incentive for people to lie.
