The home/professional distinction is valid. But it should be determined based on the category of the question, and not the category of the network that stimulated the question. There are questions some home networkers ask that belong in SF. Just don't tell 'em it's for a home network. There are other questions that should be migrated to SU. The problem with SU is that is doesn't distinguish between a "home super user" and a "home system/network administrator". Neither one necessarily implies the other.
