We're currently two-thirds of the way through the beta period. As I understand it, the site will get shut down at the end of that period if it's not considered successful. This blog post says:
We’ll set strict criteria (number of new questions per day, number of registered users, percentage of answered questions, number of people who vote, etc.) to define a site that we consider to be successful.
and this one says
We’re looking at lots and lots of metrics, but the most important ones are people and questions.
People: Do we have a lot of people visiting the site? Are a lot of people signing up? How many people are answering questions? How many page views does the site generate?
Questions: Are questions getting answered? Are they answered well? Are they answered quickly? Are a lot of answers accepted, indicating that the person who asked them was satisfied? Are a lot of answers upvoted, indicating that some third party thought they were quality answers?
Does anyone know the cutoff for success? Anyone (e.g. moderators) know what the stack exchange overlords think of the site?
The proposal site lists a few metrics along with the numbers they consider "healthy" and "worrying." Currently we're listed as "worrying" for number of questions and only "okay" for number of users and visits per day. You can also look at how we compare with other beta sites: we're currently way behind on number of questions but doing comparatively well in some other areas.
My guess would be that we should try to avoid being "worrying" in any category at the end of the beta period in 30 days. Any ideas of how to boost numbers?
