imho, sites like this are great in concept, but the chicken-and-egg problem becomes more intractable the more "broad" it is. The trouble is getting just some traction, in just 1 niche. It almost seems easier again in my opinion, to conquer a specific niche/vertical first, then adjacent areas, one at a time (as opposed to attempting to do a land-grab but see nothing stick)

I agree completely. If they saw opportunity, I'm sure ebay could clean up in this space.
