This is my YouTube subscription feed. It seems the top video and last video in my feed will show up 2 additional times at the bottom of the feed. This ends up in those 2 videos being displayed 3 times in total. When one of them is the last to be watched (and removed from feed) it shows up 3 times in a row as you see to the left. Man I literally can't remember when the feed worked right the last time. It also tends to not always show everything.
So this is my Twitter feed. I just think it's funny as hell that it wants to draw my attention to something I many have "missed" when it's directly above the "In case you missed it" box. Not only that, but I have already commented on the item. LOL.
