'clean url' vs. SEF (Search Engine Friendly)/#3032

In Mambo / Joomla this has much better name SEF - Search Engine Friendly urls. It is woth of note OpenSEF module to Joomla here.

Yes it doesn't matter if something useful is named A or B but for a lot of people clean url will be new name, SEF is much more known in php environment :-)

Just my 2 cents :-).
