The only things I found really, really useful from this site are:

Clean a little where you are.
Put away stuff now/Do it now instead of later (this really changed things as I don't have to spend hours and hours doing all the stuff I haven't done during the rest of the week).
Don't keep stuff you don't use. I love throwing things out so this one was very easy :)

The rest is crap as far as I'm concerned and her view of things made me uncomfortable.
