I have always been under the impression that mature was 'less' adult than restricted and several pages that talk about that meta tag tend to agree.

The w3c replaced that simple tag with PICS ratings because a policy could be generated with your own rules if someone wanted to get sophisticated enough to write a policy. ICRA made things a bit too granular, but, are the largest 'standards' based group that I have seen and most of the 'safe surfer' technology is based on ICRA's work.

I think with a PICS rating from ICRA and the rating metatag and some enforcement, it can be said that the adult industry IS concerned with making sure people do have a method to control access if they deem it so.

Personally, I don't feel adding a new system or meta tag will be adopted by the search engines, browsers, plugins, etc anywhere near as quickly as using a system that has been defined and in place since 98.
