Boy do I hate to ruin a good debate, but I shoot both at the same time and if I need the RAW I have it, if the JPGs are OK I can make fast edits and get on to uploads without the extra steps.
When a website needs a small image in 15 minutes, it's pretty much a matter of speed winning over fine tuning. Heck it's for a website, so it's small anyway. JPG only.
News photos have to be uploaded as soon as possible after an event, including the metadata and sometimes story line plus specific information, along with it. Not later, when I get home or when I have time to open RAWs and spend loads of time. It's intense and fun. They get sent from the location.
But, if it's going to go on some marketing site later, as editorial, then I want that RAW so I can do as much as possible to make it attractive to a buyer.
Also RAW takes longer to process when it's being shot and takes more space on the card. If someone is shooting sports and needs to take fast shots, or a fast series of shots, then it's JPG only for speed.
Sports or fast edits, all JPGs no RAW. News without fast action or in the studio, it's both at the same time.
People don't shoot with the same setting on the camera all the time, they change depending on the subject and the requirements. Same goes for RAW and JPG. I can't agree with someone who says they shoot only RAW all the time any more than someone who says they shoot TV ISO 200 all the time. You need to be flexible according to the situation.
