Let's face it: our site has pretty low activity at the moment. We have fewer than 200 visits per day, and our questions per day has dropped to less than 1. However, we've answered well over 90% of our questions, and we have almost two answers per question (note that there's often only one correct answer!). In short, the problem is that we don't have enough users.
There are many websites, blogs, forums and clubs about retrocomputing. A great deal of these people won't have even heard of this site. We need to get more people involved. But how?
If you have any ideas, post them in answers below. If you need help or to expand on them, post a question using the tag site-promotion, and link to it in an answer to this question (optional).
With all your ideas, together we can help this site to grow!
