Honestly, I've always prefered simple plain text instruction on how to apply a hack. Firstly, I want to know exactly what a hack does to my board. And secondly, I have my own way of commenting applied hacks, which enables me to make it easier to upgrade vB later on.
If someone people prefer automated installers, like based on HTL or a "blank installer" (whatever that is

), that's fine with me; I only hope that hack authors will continue to always supply plain texts file as well.
