You don't need to support alias domains.  They redirect to `*.stackexchange.com` domains, anyway.

This will match all current Stack Exchange sites.  It uses `@match` for smarter domain and path wildcards.  [`@match` also works better for Chrome][1]:

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