Paul Jones has written up a response to Matthew Weier O'Phinney's recent post on shared interfaces and the PHP-FIG. In it he talks about the PHP-FIG group itself and specific references back to the original post.

He mentions the ideas of "new thinking" and the limitations that standardized interfaces might try to impose on an application:

One is able to imagine reasons why having shared interfaces of the kind described above is in opposition to, or at best orthogonal to, better development practices and greater innovation across PHP land. Even so, I assert that shared interfaces as described, while maybe preventing an imaginable ideal in theory, instead promote an actual good in practice.

Matthew Weier O'Phinney responded with some of his own comments and correcting some of the misinterpretation of his original comments.
