It's very much a supply-constrained market, which is why firms tend not to advertise much, and why it's hard to understand the premise behind this market.

Since this posting, I've had 3 boutique firms sign up. It is a supply constrained market, but a highly inefficient one.

I believe the market is inefficient, but what I don't understand is how something like this is likely to make it more efficient.

This is, for what it's worth, my field; I co-founded Matasano and helped run it until we sold to NCC.
