You should probably add more include patterns for the other stacks.  
If you use:

    // @match       *://*.askubuntu.com/*
    // @match       *://*.mathoverflow.net/*
    // @match       *://*.serverfault.com/*
    // @match       *://*.stackapps.com/*
    // @match       *://*.stackexchange.com/*
    // @match       *://*.stackoverflow.com/*
    // @match       *://*.superuser.com/*


instead of those 2 `@include`s, in the script; it will work for almost all SE sites -- like Information Security, for example.
