We can do both, I think.

Any filtering/querying tools we build in the UI will allow for negation, too, so you'll be able to say "everything that matches X" as well as "everything that doesn't match X".  I have a lot of ideas around this you'll be seeing peek out into the product in the future.

This is actually already inside the post's metadata on the blockchain, it's just not displayed by the UI, but could easily be used to filter.
