The word isn't namey enough to me - a shore is just a boundary or edge. It could be a cliff, or a beach, or no feature in particular. Not enough of an imagey concept, for some reason - I guess because the word isn't normally used to bring an image to mind. I think of maps, shorelines; and things washing up on shore, shorebirds, and artificial surfer-speak like "let's go to the shore."
And there's the facetiously-pronounced-"sure" / show-er / Pauly / Jersey thing. Not shore that'd stop me from liking it if it clearly meant "beach." But it doesn't mean beach, so, nay.
I think it's usable, I just don't like it.
