I came across these two sentences whilst editing today, and wondered what your opinions on the correct variations would be:
They're great, I love them.
vs.
They're great; I love them.
vs.
They're great. I love them.
And
She grew up acting and singing; treading the boards.
vs.
She grew up acting and singing, treading the boards.
I'm not averse to comma splicing, and as it's a piece of website copy it may indeed be appropriately vocative, but would love your opinions on the correct constructions.
