All depends on how you are going to distribute your "topics" or "subjects".
My example was just a way to point out the relation, not actually what you
should be doing. Some people like to store strings directly, others
enumerations, others a parent+child relation. It all goes down to what you
feel more confortable with.

Correct :) - That gives you _many_ users liking many _subjects_ in one

There are going to be obvious implications on what other queries you might
need, but given your initial requirements it seems you need to tend to
distribute those models so you don't kill an indexing server with many
variations.
