The reason I have a reddit account in the first place is /r/rust. It was and still is one of the central discussion places of the community, more so today now that IRC has been killed. /r/linux is a great place to hang out as well, at least if you are interested in FLOSS related things. Sometimes you'll even see someone like gregkh chime in.

I remember at one point the moderators turned r/linux into a place where you could only post Linux news. That's when I left the subreddit, and I haven't really gone back since.
