To find something (to be) very interesting

A. I find this very interesting.

B. I find this to be very interesting.

Is there any difference in meaning between the two?

For me both of them are wrong. I will say : I find that this is very interesting.

Both are fine and I suppose Laura's is okay too. I would normally say A, though.

You can also say : 'That's cool'

You can also nod and drool.

Actually I think they're both ok.

^yeah. Maybe B gives a bit more emphasis to what is being said.

Is it Laura with /Q/ or /A/?
