I don't think we've made any graphs of user growth here. One of the things we want to be able to do is give users the ability to make Hubski feel like a small community even when we do grow to the point where this article says we'd start to have problems. One of the prevalent pieces of advice for improving your reddit experience is to find small subreddit communities for things that you like and just subscribe to them. Hubski has even been described as a "like a really nice subreddit". You have to ask around to get that kind of advice, though. When you first start out you're just thrown into the mess of defaults and an alternative experience isn't shown as an option. Hopefully we'll be able to accommodate different user experiences, from those who want to feel like they're a part of a huge community, to those who just want a quiet space to discuss their few niche subjects.
