Hi I'm new here what's up

I think this site is a really neat concept, especially because the quality of discussion on Reddit has really deteriorated (which has happened concurrently with Reddit's shift from discussion and news to "repository of Internet culture"). I like online discussion, and IMO this site's design is better than Hacker News, so I'm probably going to start using this site. Is there anything I should know about this site? This is my first post and I'm not too sure how things work.
