it seems to be much less common to add that 'd', eg 'mix berry flavor yoghurt'.

Adverbs are a sticking point too. "He did that more quick" (gaaaaahh, but I have actually heard that one); "Drive careful" - that sort of thing.

Also the phrase 'Can't be beat' (i.e. without the suffix -en) makes me want to slap people.

'I won't be beat' is the catchphrase for a local mattress store.

I don't know if it's 'wrong' or just different usage, Americans seem to say things like "I wish I would have done that".

I wish I would have said that,

My wife occasionally says "I seen it" instead of "I saw it" but that's said wrong in Belfast probably more than here

One I don't like (which is probably also pretty universal) is saying things like "I am liking this" instead of "I like this". Not sure if it is wrong but it never sits right with me.

God knows what Americans would say, but 'on the cards' means it's possible or likely' that something may happen.

'In the cards' presumably means somebody has had his or her Tarot cards read...

So 'in the cards' is the polar opposite of 'on the cards' then

Yes I'm not lovin' that one.

Vom-worthy

Don't know. However, when Americans "queue up" -- people on the East Coast tend to say "stand on line" while West Coast people tend to say "stand in line." I've heard people actually argue about that one.

Cool - so people in NYC have solved space issues by making people queue standing on each others' heads?

I like that one

One I found weird. Was asking the wife what she's been up to and she said "Visiting"
I said " Who did you visit"
She said " My sister came over"

Apparently if someone drops over to your house to see you you are still "Visiting" with them ? ( At least in Illinois where she's from )

Yes I've heard that. Maybe it's the 'with' that means one has stayed at home.
