Couple of related ideas...
Firstly - I generally watch one show at a time and thus "currently watching" normally only has one thing in it, however I have started using it to also note what I want to watch next (ya know, it cuts down the no-kdrama down time between shows :-P ) and it occurred to me that it would be good to put an order on the "plan to watch list". I'm sure i'd be floating that order around on a daily basis but it would be a great place to start when thinking about what I want to watch next.
Second - I maintain a spreadsheet of my own which lists *why* I want to watch something, e.g. was it because of a particular actor/actress and if so which one(s), or is it because the trailer/marketing etc make the story look really interesting etc, or was it because it was specifically recommended by someone and if so why. It kinds feeds into the above about wanting to have more intel about what show to watch next.
I'm probably overthinking the whole thing but thought i'd share the thoughts anyway :)
Thanks for providing an awesome site :)
