Dads and Housework

I've been sitting on this Working Father post on the dads and housework for a few days now. I pulled the source report, and I'm just still not sure what to make of it all. Is it good that we're up to seven hours of housework? From a gender equity standpoint, it's bad that dads are lagging behind moms (more than 21 hours a week), but 21+ hours a week on housework -- no matter who is doing the work -- seems like overkill. Surely there are better ways to spend three hours a day.
