When CamelCase matters
As editors, we know all about the perils of global search and replaces, because of the potential for unintended consequences. There’s a storm brewing in the WordPress community about this very issue: the main developers have set the software to automatically change all instances of WordPress, or any other form, to WordPress [capital ‘W’, capital ‘P’].
As editors, we know the official form should prevail in text, but the unintended consequence of this global search and replace is that it changes links in the program to directories on people’s websites—from wordpress to WordPress—which has the effect of breaking the link. The blogging world also has trouble with the concept of changing people’s writing, but that is something editors are comfortable with when done for the right reasons in the right way.
