BBC America's "Mind the Gap"

So my first piece is up on the BBC America web site. "Mind the Gap" is a column explaining American things to Brits (and vice versa on occasion.) I wrote a piece about volunteering, in my usual don't-take-this-seriously, tongue-in-cheek fashion.
And I'm reminded once again, of why sarcasm and general piss-take should be applied very lightly in the USA. Read the comments and you'll see what I mean.
Sometimes I give up.
