Think about the future too though. Facebook strips exif and may have resized/recompressed your images. 20 years from now when we can do more super cool things with that data, the data won't exist in your FB photos. Tangentially related, this is why I shoot RAW. Not because it might give me better pictures today, but because it WILL give me better pictures in 5-10-20 years. You can take a RAW today that was shot 5 years ago and pull detail that was impossible to pull when it was shot, and that ability will only improve.
