Huh? Not doubting you here, but why do you think that? Seems like an obvious turn-off to me"The crowdfunding page is slapdash or poorly-written."
After many years of running and pledging to Kickstarters I'm convinced that a page without typos does worse than a project page with typos.
The most important thing for me is this: does the Kickstarter have a full functional quickstart or preview of the game? if not, it isn't ready for prime time and they should not be crowd funding it yet.
Poll options added, feel free to update your votes.There are several options I selected up there that that would stop me, but honestly, the most common one is simply that the cost of the base whatever-it-is of the kickstarter is higher than I was ready to casually spend on first blush having just learned of it.

I've seen some doozies over the years....everything from the occasional typo or grammar error, to upside-down images (yikes) and broken HTML tables. None of those were deal-breakers for me, and the creator is usually pretty quick to fix them when they're pointed out. But when those errors are in the teaser photos of the actual project--or worse, the "teaser photos of the actual project" are obviously Photoshopped stock photos--I run for the hills.From spotting typos on I think every Big Kickstarter page I've seen.
