Alright, here is some constructive criticism:

You shouldn't implement such large-scale changes without some sort of Preview/Trial first. You should have some sort of "sandbox" that allows you to test these changes and weed out all the annoying issues before hammering the entire community with them.

Wiki pages have a Preview button. Why don't you have one too?
