Not an error or anything. I was just frustrated today and yesterday having to scroll through stuff I've already viewed. Reddit had one thing I really thought was a good idea. They had an option to hide stories that you've already voted on. Then your feed is only new stuff for you instead of most of the stuff is the same shit read already. I think this would also save bandwidth since you wouldn't have to load the old stories and people wouldn't have to load 3 pages to get to the unread stuff, might also save the storage devices wear since the stories will not be retreived also. The cpu will be a little more sorting the stuff but after that it's just loading new posts for the user.
