I think it's more focused in the sense that you'll have many more "serious" people looking at what you write, at least some of them will be domain experts in the topics being discussed. This causes people to post much more conservatively and less frequently than they would do on reddit. The flip side of that is that reddit will throw up discussions on things which would never in a million years show up on HN, this one today for instance I found very interesting https://www.reddit.com/r/AskReddit/comments/4g1pgu/serious_trans_people_of_reddit_what_was_something/ https://www.reddit.com/r/AskReddit/comments/4g1pgu/serious_t... I personally don't know of another "forum" where a post like that could happen and get such interesting responses.
