Unless you don't use Firefox and you tend to have a lot of dot files that you hack around with in your home directory. Then it starts to seem pretty awesome.

Chrome runs Greasemonkey-scripts, too. They are automatically converted to extensions in the background. Works very well. ( http://blog.chromium.org/2010/02/40000-more-extensions.html )

But I wouldn't call this useless. It's just another approach.
