Well done so far, we've gone public now. But not all is well.
We have very few visits every day, and we have few users in total. There is a great quality of questions and answers, but quantity is not our strength. Have a look at our Area51 page.
I'm not so sure about that. Have a look at the list of users, beginning with the newest one. Doesn't look like the great rush to me, yet (although, admittedly, it is very early to make predictions).
So my recommendation would be:
Invite people you know, post on veggie forums, spread the word, talk about it. We need a lot of new users. Ideally active users who ask and answer, but already more people who upvote good content would be great.
