Another recent request pointed out an issue with the current system: answers are limited to only 30,000 characters in length.
While I personally do not feel that posting very large amounts of code in answers is particularly desirable, I do foresee other circumstances where it might be desirable to have much, much longer answers.
Consider the longest pages on Wikipedia: they exceed SO's current limit by over 10x, and they're dominated by lists. Programmers love lists. Programmer cartoons, jokes, blogs, every function in PHP... there are endless possibilities (although i've no doubt someone will soon start a list of possibilities).
And SO will inevitably fail them, unless the answer length limit is removed or increased.
Sure, we could do the usual "one list item per answer" thing. But that has an even worse effective limit, in that you only cram 30 answers on a single page, and junk up each item with irrelevant things like the author's name and icon. Printing these is frustrating at best.
So for the good and healthy future of all SO, please, please increase or remove this arbitrary, restrictive limitation from the system!
