Didn't see a specific thread on it, so thought it was worth discussing.
My main question is anybody actually using it happily?
I experimented with it and my takeaways are:
1) It does give notably more push-around room than a jpeg and at similar stored file size, +2
2) The work required to get it into a jpeg so it can be posted is literally the same as if I start with a raw, -2
3) It does not have the push room or latitude of a raw, -1
4) It isn't widely accepted (yet?) except in a few raw processors like LRc or ACR. -2
My conclusion is it simply isn't worth it, at least yet. If and when it is ever directly editable and upload-able to most websites, I will take another look. For me for now, I stick to raw...
