F U S I O N

I was recently asked my opinion on this by a newbie and I was curious as to some other people's opinions...

In this day and age, with so much compitition and declining sales, would you choose between building one big mega niche tgp-type site with lots of handmade galleries and no hosted galleries (and no outside submissions) or a bunch of single niche sites with minimal handmade galleries and mostly hosted's (and no outside submissions)

Only between the 2..... And why?
