^ That's a huge turnoff to me too.
As far as chapter length goes, that's never been an issue with me, except for the extremes - chapters that are only 100 words long and chapters that are, like, 10,000+ words. 100 words is hardly enough to contain anything with substance, and 10,000 is a little excessive, though I probably have written a few chapters that long... usually mine end up being more in the 2,000-5,000 range, I think.
Word count isn't something I pay attention to as I'm writing, though; I go more by pages and natural scene breaks. I would never end a chapter just because it went past 3,000 words, and I would never not read a story just because its chapters were longer than that, either.
In published fiction, 3,000 words equals roughly 12 pages, which doesn't seem like that long of a chapter. It depends on the author, but a lot of the books I read have chapters of 20 pages or more. But just as I don't count pages in a chapter before I decide whether or not to read a book, I don't even look at word count when I decide whether or not to read or continue a fanfic.
