Well, I've discovered that 10,000 characters is not actually 10,000 characters! I've edited down my post to 9500 characters, including spaces, and this system still errors out claiming it is too long. Why is that?
As for the inquiring person who asks how can one possibly need 10K characters to write an article, you really need to read a bit more beyond comic strips. I barely have over 1,500 words. Didn't you learn how to write 1,500 word essays in high school? Or is "I REALLY (written out 1,400 times) LIKE IT" more your speed for a detailed, well-written product review?
