The broad brush arguments are clearly
a) people will get more polished as n increases
b) ... but maybe less fresh / original
c) ... and as n increases things will be published based on their reputation
d) ... and eventually the 'brain eater' will get them
Interestingly, Mr Snips and I both came up with the same number.
So clearly this needs a poll. Any explanations, examples in the comments welcome of course.
Voting does not implicitly or explicitly imply that you think this is in any way a sensible idea.
If you had to only read the nth published novels of all authors, what would n be?
