My biggest gripe with the Reddit UI is having to continually click expand to see nested/additional comments. It makes it difficult to read comments on a topic.

My biggest gripe with the Reddit UI is having to continually click expand to see nested/additional comments. It makes it difficult to read comments on a topic. I much prefer the HN approach of open by default with a collapse/expand button. It used to be that clicking outside the central border of comments would navigate you back to the subreddit, but it looks like they have fixed that.
