From Expert Click:

[Infidelity expert Ruth] Houston, “No matter who is cheating, or accused of cheating, the public always wants to know more. People have an insatiable appetite for anything related to infidelity, cheating spouses, and extramarital affairs – especially if celebrities, sports figures, politicians and others in the public eye are involved”

Bingo. Like rubbernecking after a car accident.

“If the TLC Network wants to keep the ratings from slipping any further, they need to capitalize on the infidelity rumors by putting a positive spin on things,” says Houston. “Handled properly, there are valuable lessons that can be learned on Jon and Kate Plus 8″

She’s talking about their record breaking season 5 premiere. Since then the ratings have returned to normal. But you have to wonder if TLC (which incidentally stands for The Learning Channel) would be willing to put a positive spin for an obviously teachable moment.

Update: Actress Archives nails it.

If Kate and Jon have taught us anything, it’s that nobody becomes a truly big star until their marriage starts to fall apart.

Update II: There’s an announcement in the works.
