Minor Powerlevel, I watch those shows because I work with children in those age groups and I want to be sure they're not watching utter shite. I have a whole system of bonding and developing early language skills based around watching the shows they enjoy and discussing them in an age-appropriate way (ie: Fireman Elvis isn't very good at being a Fireman, is he? Why was Percy sad when Gordon took his coaches?)
I agree with about half of the list. Boobah is vaguely sinister and the Mickey Mouse Clubhouse is the bane of any childcarer's existence. You really can't just dump a child in front of the TV and then wonder why they're not talking beyond repeating 'Hot Dog! Hot Dog!' all day every day.
