If there were to be discussions at phppatterns.com I suppose the discussions would need to remain as comments based on articles submitted.
Though in saying that, an article could in theory be based on a number of people working on the same end objectives here at sitepoint for example, no ?
Have a read at what HarryF has to say about the continueation of phppatterns....
As a development communitity, HarryF has a valid point in saying that PHP doesn't have a spokes person as such, nor a place where a Java developer for example, can go to look at application development w/ PHP; other than php.net which isn't really appropriate - non development issues are amiss, and it's more concerned with the actual language and it's distribution.
So this Java developer is lost except for a few developer sites going about which in fact discusses PHP in more general terms; other than enterprise sized application development.
That's were phppatterns.com comes into the equation right ? HarryF has started the ball rolling by specifically gearing the site towards this area through the use of OOP - the building blocks of application development - done the proper way of course.
