I edited the post from how it was originally posted. The point I was making is not that jpegs per se are bad but that SOOC jpegs are deficient in ways that I think are critical for general internet use (exceptions mentioned already). Everyone seems very excited by the high quality of 1Dx2 SOOC jpegs but to me they are almost useless without metadata (see above for specifics) and watermarking.
I think the pro sports/journalist photographers and their agencies will be the most excited about the SOOC JPEG improvements (and they are perhaps the single largest market for 1D/D5-level cameras). The deficiencies are not an issue for them and they can't wait around while RAW files are being transferred over.
