All get app errors for me just now. Hoptoad showed an error (NoMethodError: undefined method `strip!' for nil:NilClass), but from a few minutes ago, and i checked the last example moments ago.
D'oh! Lew and I made an unnecessary extra tweak yesterday (when we were fixing up problems that stemmed from my original paging bugfix) that we thought was clean up. It was my idea :(
