I've said it before, and I'll say it again now: the best thing we can possibly do for our site is to ask questions. Why, you ask? Let me explain.
Asking well written, on-topic questions consistently over a long period of time can
- get us much closer to hitting that necessary 10 questions/day marker, and thus, much closer to graduation.
- increase the chance that a particular hot question on our site will be displayed on the Hot Network Questions bar, increasing the chance we get traffic from other SE sites.
- help us more accurately determine what the scope of our site does and does not include.
- can help some users reach 25k rep and over (which is helpful for graduation so that it's not just moderators who have access to most moderation tools)
In other words, there are countless positives to asking questions and very few negatives.
Asking questions isn't the only thing we should do, however. Once our advertisements start rolling out to related language SE sites, we should expect to see visitors from other sites here. In addition, we might even have some questions migrated from other sites to LL, which could bring the OP and some of the answerers to our site as well. Both of these things take time to put into place and to reap the benefits from.
All in all, keep asking questions and promote our site wherever possible (in a nonintrusive way, mind you!)
Rome wasn't built in a day, and we won't graduate in a day either. Stay patient and positive and we'll get there.
