I got Adam to look into the settings for this. The ratings info doesn't populate until the site's been in beta for 30 days. We want people to focus on the work of building a site, not getting graded on it.
So, not a bug. Just have to wait a bit.
Ideally you would try to share your proposal to other communities that would benefit from it (not pre-existing ones on SE). Anyway, if you can't get a community together outside of the SE ecosystem, advertising on SE probably isn't going to push it over the edge.
