Comments with progress timestamps (in e.g. XBMC)
When you are watching something and you see a specific scene, it could be neat to have the ability to post a comment for that specific time in video.
E.g.
Comment: "Best quote ever! owned!"
Stamp: Game.of.Thrones.S01E02.720p.HDTV(00h27m57s-00h29m07s)
