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:
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, 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.
