WordPress is GREAT blog site software - and that is sometimes the problem. There are many potential users out there who want to set up sites which never accept comments and, instead, want only to post news. Currently, to remove all traces of comment features, links, section headers, "No Comments" messages, etc. etc., requires extensive editing of php files and style sheets. Every time the user subsequently changes themes, this process has to be done all over again.
It would be nice if a future release of WordPress contained a checkbox in the configuration page which allowed a user to totally disable all traces of the commenting feature on every page. Future theme authors, of course, would have to pay attention to such a feature and adjust their code accordingly.
Who would want such a feature? Anyone who has a fair amount of news type posting and no desire for feedback, examples: municipalities, theaters, e-commerce sites, news pages, etc.
