Oddly, I don't consider that a step up.
MST3K was a brilliant show. A lot of talented people put their hearts (and wallets) into it to make it work. It was a work of great creativity and passion.
AFV is... well, it's milquetoast. It's pre-digested food. It has about as much passion as a gas range hob.
Comedy writers aren't exactly considered celebrities either. An old joke about Hollywood goes something like this:
Producer 1: "If a comedy writer falls in the forest, does he make a sound?"
Producer 2: "Who cares?"
I suppose that having a regular gig writing for a show has its good points-- Steady paycheck, insurance, working in "the industry"-- but I just can't believe that going from your own show to being one of a bunch of people that never see the light of day is a happy thing.
Maybe he's fine with it.
I know I wouldn't be.
