For now you've got a method of getting people there, even though it doesn't scale (I'm guessing you've read PG's advice on this[1]). I'd say that what matters right now is that those you're getting on your site, are returning and active. Is that 5% growth in signups, or in something else? Are those members who you've successfully brought in returning every day? Do you have any indication of whether your members find value in your platform? You say you have no delusions about "going viral" - and indeed you won't go viral in the sense that a meme from 9gag goes viral, but communities do often depend on their members to refer others there. For that to happen, your product must provide good value to those members. Talk to your members, if you aren't already, about how valuable your platform is for them. And while you're talking to them, maybe find out where else they hang out too? You'll probably find new places to recruit members from, and perhaps think of new ways to grow. Good luck!
