Not really related to the story, but can someone explain to me why Americans put '$425MM', where does the second M come from? Here in the UK we'd just put '£425m'? Just curious because I saw DHH use MM too.
I believe the appropriate abbreviation is "$425M", not "$425m". The AP Stylebook avoids the issue altogether and dictates that million, billion, etc. should all be spelled out and in all lowercase.
