I don't believe Reddit will be the last big social news website but I don't expect them to accomplish much more. They seem afraid of making changes and losing users like what happened to Digg.
It leaves the whole market open to whoever else can do a better job. I doubt anyone is going to leave seemingly overnight like Digg -> Reddit but if someone was to start small and grow.. there's a lot of room to accomplish better things.
I'm working on something like this with a couple of others but it's too early to say whether we'd ever be a viable competitor. There's certainly a possibility though.
