Super User versus Unix and Linux versus Ask Ubuntu
If you see any Linux-related question anywhere on SE, and is in the wrong place, is the choice of destination site arbitrary? Both SU and UL (unix-SE) are on-topic and I suppose the final destination is affected by the fact that UL isn't as famous, not to mention that it is not even offered by the migration dialogue?
One thing that has been noted by many is that questions tend to have superior treatment when they reach UL as opposed to when they reach SU, so maybe we should now prefer to send such questions there instead, or at least offer it on that dialogue?
