As a graduated site, we can set up (a limited number of) so-called migration paths. That is other sites on the SE network that show up when normal users want to close as "offtopic because it belongs on another site".
That is, community moderation will be able to migrate questions away, to a limited set of target sites.
The question is, which sites do we want to have in that list?
FWIW, here are our stats for the last 90 days:
- SO -- 7
- math.SE -- 4
- cstheory.SE, SU -- 3
- english.SE, stats.SE -- 1
Things to think of:
- Which targets are most important in terms of volume?
- Which targets are unproblematic w.r.t. our knowledge of their scope? (We don't want to migrate questions to a place where they are not wanted!)
- Do we want offer a low-resistance path for moving on-topic questions away to sites with overlapping scopes?
