I also think if people are wanting a serious critique they should post up the EXIF data. It shouldn't be mandatory though IMO.
A serious critique of art has very little or nothing to do with what is contained in the EXIF information.
EXIF information is really mostly only helpful when diagnosing why a particular image has failures in the technical execution space... depth of field, motion blur, camera shake. harsh shadows... that sort of thing.
This means that most of the more experienced folks on here will gain no real benefit from posting the EXIF information, and thus will have to go through extra steps to post their images, while the newer folks who stand most to benefit from it will actually get some extra info now and again as a result.
Therefore, mandating it will, by sheer logic, weed out posts by more experienced photographers and, by process of elimination, will appear to make the traffic of the less experienced folks more prevalent.
I know OP meant well and I honestly mean
no offense... but this is a
bit silly. We've dealt with non-mandatory EXIF information (and that mostly contained in - and read from) the image itself. It's been absolutely fine. And on the very rare occasion that someone either couldn't read it or couldn't find it, it is asked for and usually provided. Making this mandatory isn't going to work, and really isn't going to happen. All this thread is going to do is likely devolve into another angry spitting match, and TPF has had enough of them lately I think.
I would suggest to OP that he just go with what works for him and we just sorta shove this thread under the rug and move on.
