Cool poster.
Thread drift: "then" <> "than", "then" <> "than", "then" <> "than", "then" <> "than", "then" <> "than", "then" <> "than", "then" <> "than", "then" <> "than", "then" <> "than", and "then" <> "than". Slight goober in an otherwise neat poster.
Getting real tired of seeing that, even in news stories supposedly written and edited by professionals. I suspect TDPTB will change the dictionaries in the near future to accommodate this common usage.
