I've noticed that posts tend to be more technical on Lobsters than on HN. For example you'll rarely find posts about gravitational waves or medicine Nobel Prize (to take some examples in the current HN top posts), it's more about programming, software, technical stuff. Quality is good in general both in terms of posts and comments, so it's a good complement to HN.
