yeah, firstly is firstly on my list.
getting pedantic for a moment, isn't "have got" actually a contraction of "Have gotten", = "have obtained"? If so, then yes it could have an independant use, but whenever I've heard it, it simply means the same as I have. Which to my ear is just linguistic laziness. Using words without bothering to know what they mean.
I realise that language changes with habit, but "impact" is not a verb, it is a noun with a specific meaning, which is NOT effect (nor, for that matter, have effect upon).
Verbing weirds language.
