Some time in the next week (ish)

I think I'm gonna revamp my tags a little bit.  Mainly, I'm going to go back and add pairing tags, but I might also change to fandom: once upon a time type tags rather than just once upon a time type tags, but that's mainly just because I think it makes things easier to find, and I have enough tags now to warrant that kind of change.

But I want to ask what you all find most useful when you're looking through the tags on someone's journal.

With pairing tags, do you prefer them to be just on fanworks about/with that pairing, or on any post where the pairing is discussed (i.e. shipping meme entries or reaction posts)?  What about character tags?  Do you think they're useful, or do they just clutter the place up?  Personally, I can see pros and cons to all of the above, and I'd like to know what you most like to see when you're using tags.
