The Washington Post has a 'Arc Publishing' division (essentially, from what I can gather, a digital news delivery as a service company [1]). One of their clients is the LA Times [2]. In other words, the quality of the LA Times's digital platforms, in theory, is (or is near) equivalent to the Washington Post's.
