I personally don't like the idea of having to wait one week per chapter if in one year it's all out, for example. Particularly if I have to pay for getting frustrated :P But of course, I follow mainly manga scanlated series, series which last for years and which get uploaded when the little bastards of the fansub decide to take their job seriously (usually the editors and typesetters are at fault, we translators ALWAYS work properly and in time
).
