When you are doing polls like i did, the alphabet song poll, you have to scroll down to the last answer to find out which letter you use, if the last comment it would save all the complications of answers getting mixed up
Also if you ask a question and people give you replies if the right answer is down the bottom and can't see it you might make the same reply....
I know it's not a biggie but there will be lots of polls that will benefit from last comment first...
