For this I disagree with you Catchlights, I used to feel the same only a few years before, but my opinion had recently changed.
Consumer based photography would mean direct to consumers, ie not a business-to-business deal. ie, portraits, weddings, family and babies.
We neednt look far. Hart seems like making good business... For instance baby photography, people used a friend for their first child, realized it not ideal, and the child already grew up, they aren't making the same mistake with the second baby.
Somehow, it seems like the 'anyone can be a photographer' thinking is starting to fade and people are growing out of it, exactly because now everyone knows everyone has cameras and people are looking beyond camera owners to professional service providers.
Business to business on the contrary, seems to have slowed, maybe its sectorish to my experience and client base, so I can't tell for sure. I may be wrong about consumer market too but I hope I am not.
