Bridging the Unbridgeable 
I’ve just come across this letter from the Irish Times (the paper is a goldmine for complaints) on have went as one of the horsemen of the grammar apocalypse (ie. the death of the past participle, along with the death of the adverb, etc.) http://www.irishtimes.com/opinion/letters/on-the-decline-in-grammar-1.2275386. The problem might not remain American for long after all.
