photosen: I appreciate these articles but this one... Too verbose and not very original. Hint: building an audience à la Facebook? Not working... A photographer may be reaching thousands of people, they are still not going to hire him or her.
As for the economics... I think Canon, Nikon, Pentax need to integrate a way of quickly sharing to the web from "real cameras" without falling for the trap of having an OS that may do a lot of things but ends up doing most poorly...
I realized the other day I was missing something by not using my main slr for social media. I have an eye-fi card, and tried installing their android app. I then set my camera to raw + jpg so I would still have the raw around if I wanted it, and set the eye-fi to only transfer over jpgs.
It's not instantaneous, but it transferred straight to my phone, where I cropped it and uploaded it to facebook. This was way faster than popping out my memory card, copying and importing into lightroom, editing, exporting, then uploading with a browser.
It means popping in a different memory card every time you want to use your SLR for social media, but it's a decent solution until the camera manufacturers bake it into their bodies.
