Now I understand why some Gonzos here do full quotes of long posts only to add a "Well done!" or similar.
Well the post quality counter does ignore quoted text so those quote pyramids don't help them. I also updated it to exclude all whitespace so people don't try to cheat it by adding a ton of spaces to the end.
I'm sure you will find a better algorithm yourself, but in case you'd like some input, feel free to PM me. I have done some "text quality metrics" in the past, so maybe you could get some inspiration from that.
Sure, help would be nice.
