What is "on-topic"?

We seem to have a lot of new users, probably the Zero will increase this.
Lots have little or no Linux experience. As a consequence they ask beginner (or even more advanced) Linux questions.

Questions about Raspbian, even if they are general Linux questions should be OK as they are about "Operating Systems built for the Raspberry Pi".

Many get referred to <https://unix.stackexchange.com/> - this can be intimidating to such users. Maybe we should answer more of these on site and actually use the "Linux" tag.
