Agree or disagree: Reddit would be better off blocking sites like quickmeme

It is glaringly apparent that memes are ruining (or have already ruined) Reddit. Would blocking content from sites quickmeme be enough to save the site? I've been lurking Reddit for over five years, and with the drastic decline in good content I don't see the site lasting for much longer than another year. Remember what happened to digg? I do. While I don't in any way support censorship, I do believe that Reddit has lost the base idea on which it was founded, new and interesting content. Discuss!
