I just posted 1/2 a comment on someone's photo because I acidentally hit enter in the middle of typing it. I have tried 3 times to post the rest of my comment so it would make sense but every time it says "sorry you cannot post another comment so soon" It's been like 15 minutes so I think it's just not going to let me do it right now. Guess I'll just try again later...

thats happen to me before. i figure out that you have to close the tab or window and then go back to it and you will be able to comment again no problem.
