I just experieced a pretty weird youtube bug. I kept my video unlisted and after I added some views I published it. That was 24 hours ago and it's still not shown in the youtube search. Even when I put the filter "uploaded today" i can not find it. That never happened to any of my videos and I have uploaded hundreds that way! Maybe it's just an uncommon error or something? I just uploaded the same video on another account and will publish it tomorrow. Hope it works then since the video is exploiting a hype which is dying soon.
