It's well known that most social media, and very much so for Reddit, are primarily consumed by lurkers. There's loads of daily users that don't even have an account because it's not necessary. The lurkers may be good for ad revenue, but they don't make the content. You need the active community there to produce the content that lurkers consume. Without the community, the lurkers aren't going to step in and do it themselves, they'll just stop visiting Reddit. So yes, I'm sure the balance looks like 95% lurkers and 5% community.
