I don't post many videos anymore, because usually when I find something I feel is worthy of the sift I find that it has already been posted. But twice now I've posted a video that didn't get a single vote and expired to my personal queue, then days/weeks later I come to the sift and see someone posted the same video and it's now on the top 15 list after a few hours of being posted, using a nearly identical title and tags as my post.
