Yes. The tags are organized with 2 kinds of relations sub-tags and related tags. This
enable to explore the tags universe and to organize them.

No. For instance we could put all the tags in a flat tree (i.e. all the tags at the same
level) but then it would be rather tedious to find something.

Here are some examples of tags branches as I see them:

Licence
    Open Source
        BSD
        LLGPL
        GPL
        MIT
        ...
    Commercial

Operating System
    Every OS
    Unix family
        Linux
        FreeBSD
        ...
    Windows
        Win32
        Win64
        WinCE
    ...

Library
    Text
        Typesetting

So with these tags cl-typesetting will be tagged as: "BSD" "Every OS" "Typesetting"
And this will imply the "Open Source" and "Text" tags.
