I think Manneca was one of the earlier ones in the thread to point out, it's really just a question of "what software do you use to process your image."
JPG people would have to answer, if they were honest, "I use the software in my camera to process the photos."
The RAW people would answer "I use the data from my camera, but I process in Lightroom."
Yes, you can use RAW to "salvage" some marginal shots, but the real magic of photography is more than just making the shot meet some qualifications such as sharpness, color, exposure, etc.
To take a great picture, you have to find an inspirational setting and subject, choose the story you want to tell, set up and try multiple angles, determine which tells your story best, set up additional exposure equipment, take an image, then process it, and post it on Facebook for a few friends to like.
Or, sometimes you just look up, see something cool, and push a shutter button, and post the .jpg from your phone in the parking lot.
I shoot RAW, I think I'll keep shooting RAW for the foreseeable future. Storage space is cheap, and I don't want my camera to make the decision on what pixels to throw out. The camera is old, and hasn't been improved at all. Since I got it, two new version of Lightroom have been released, and more are on the way. Not to mention, with Lightroom, I can use printer profiles and see what the file will look like printed, where it's going to be printed. The .jpg processor in the camera, has no clue. White balance isn't about getting something right or wrong, it's about what you photographed and where it is getting printed.
But, one of my goals with photos is to keep getting published in magazines. My favorite spot to be published is on the cover. RAW is worth it for me, and it's not because the original photo sucked, it's because Lightroom does a better job of exporting the image I saw in my head, than the camera does. It's a more powerful processor than the camera, and the end result was a more powerful front cover.
