Why nuke...

I have been using Xaraya now since before Xaraya had a web site.

Even then with work it was better then any nuke and most commercial CMS's
out there.

So I am wondering why are people still using nuke?

Not trying to start a war, but trying to understand the logic.

I have a test PHPNuke and PostNuke, neither have changed much in a year.

My guess is ease of use for the administrator and or end user. But really
for the admin a little work learning and Xaraya is easier to use, for the
end user, with the right design and set up it is much easier then Nuke.

Any ideas please share them.
