I disagree. I'd even argue there really isn't a focus after all. It's a massive site with an even larger userbase.
For example, once you leave the top 10-20 subreddits, you encounter places like /r/askscience, /r/books, /r/hiphopheads, /r/dataisbeautiful etc.. All primarily discussion based subs with consistently in depth threads on esoteric topics, even by HN means.
That's not even mentioning the live updated threads on huge news stories, or all the sports subs with their game threads and on the second updates. It's a viable resource that's looked down upon because of the front page, and that blows.
