Is there like a reddit style plugin for Discourse? That makes it look very similar to a subreddit?
No, there is not. That said you can achieve images in topic lists using Topic List Thumbnails Theme Component, and we will add a similar sorting algorithm for topics in the next version. But at the moment there is no plans for the threaded style for comments in a topic.
Aha okey, is there any particular reason why?
Aha, I don’t see why it couldn’t be an option though, but oh well
Another question, is there a plugin (except making threaded posts) that make it look reddit like (reddit classic) and with a sidebar option?
