I for one don't mind it. I went 4 days/week in March and it changed my life for the better. I like my job but that one day off extra gives me so much flexibility. I can do all errands on Friday and then pick up the kid from school and have the whole Friday afternoon and weekend to spend with them. That means that during the week I finish work and can spend time however I want instead of doing chores...
In my opinion this 'message' should actually be pushed more and people encouraged to try it. If that means shilling some website with 4d/week jobs...so be it.
