You totally can, the HN dupe detector is less than reliable. Submit something interesting at night and you'll often see it submitted the following day by someone else. As a more general point, the fact is that if a discussion doesn't take off while an item is on the front page shortly after submission, it probably never will. The page sorting algorithm ends up prioritizing recency and traction. I agree this isn't ideal.
