After half of the official 3 month beta phase, let's recap some numbers:

With 11.9 questions per day, we have an excellent influx of new curious content.

questions per day, we have an excellent influx of new curious content. Also, 90% answered questions is excellent and indicates a healthy beta.

answered questions is excellent and indicates a healthy beta. The 929 visits per day is okay and increasing steady and I'm quite certain we will reach levels of several thousend hits per day very soon, as ethereum is quite a hot topic on the web (some days ago it was at around 600ish).

visits per day is okay and increasing steady and I'm quite certain we will reach levels of several thousend hits per day very soon, as ethereum is quite a hot topic on the web (some days ago it was at around 600ish). The 1.5 answer ration is okay, but shows we could use more expertise on the site, e.g. more experienced users contributing high quality answers.

All that looks, as I said, okay. But the real issue I see is the lack of a solid user base and a very slow growth of the user base. For graduation we would require at least 5 users with at least 10k (access moderator tools) reputation and a solid group of active users with at least 3k (cast close votes) reputation. How can we achieve this?

How to gain more users and more quality answers at the same time? How to generate more overall site expertise?

I would like to have one idea per answer and everyone can use up-/downvote the proposals.
