What does it take to be lucrative in the freesite game nowadays?

Some very excellent advice in this discussion. The fetish niche comments in particular caught my attention.

The premise of the question is strictly building and submitting free sites, but there are some other things that go along with that which aren't strictly building and submitting that also need to be done in order to maximize that effort. Namely a hub site or sites and all that goes with it, such as link trades, traffic filtering, etc.
