One thing I've noticed in close-voting is that if the questioner mentions that what they're doing is in their home in any way, it gets voted off-topic. If it's about the network itself, it gets shoveled off to SuperUser. [Right now the SF Faq reads][1]:

> Server Fault is for *system administrators* and *IT professionals*, people who manage or maintain computers in a professional capacity.

And under the 'What not to ask' section:

>If your question is about …

>   * Programming, not just scripting, ask on Stack Overflow.
>   * General computer software or hardware troubleshooting, ask on Super User.
>   * Web design and HTML/CSS layout, and your job title is "designer", ask on Doctype.

The FAQ does not in any way discourage asking questions relating to:

 * Networking outside of the professional workplace
 * Running servers at home in any way

The one gray area are questions which could possibly relate to the kind of continuing education sysadmins need to do. [A lot of us have servers at home][2], we just don't consider them professional. This possibly is the topic of another Meta post.

The reason most commonly cited for closing at-home questions is largely, "this is a professional sysadmin community, and stuff at home isn't professional by definition." That attitude is not enshrined in the FAQ at all

----
Specifically, I'd like to modify the What Not To Ask section:

>  * General computer software, hardware troubleshooting, \*or home networks\*, ask on Super User.
