As described in this news item, a new Metaculus "domain" system has recently quietly gone live.
In short, the idea is that it is now very easy to create domains, which create sub-divisions of the full metaculus community (which we've started referring to as "Metaculus prime", or "MP"). The idea of a domain is:
-
Each question has a set of domains associated with it, and it appears on those domains.
-
Each user has a set of domains to which they have access, but all users have access to MP.
-
Each domain has a top-level URL of form [domain].metaculus.com
-
Each domain has its own leaderboard, and can have some other customizations, such as a few different look-and-feel options, different categories, etc.
-
Users carry some of their information (levels, powers etc.) across domains but not all of it (with details TBD.)
The hope here is that domains can be used in a few different ways, e.g.,
-
By a group or organization that wishes to create a set of questions private to that group, but optionally cross-post some of them to MP.
-
By Metaculus or another group wishing to create a domain focusing in much greater detail on some particular issue, where some of the "top line" questions would be cross-posted to MP, but some finer-grained or more technical questions would be domain-specific.
We're currently in the process of integrating what was previously a private instance, ai.metaculus.com, into the domain system. So you'll probably start to see some cross-posted questions soon.
This discussion question is to invite feedback. For example:
-
Questions about how domains work?
-
What uses do you see for domains?
-
How should some of the details work? For example:
-
Should you carry your level and score across all domains, or should it be individual to the domain, or both?
-
What happens when a question is cross-posted when it's already opened?
