I understand not wanting people to look at your stuff, makes me nervous too.
I'll tell you why I don't like EXIF.
When some people look at a photo, especially for critique, they judge the photo based on the mechanical aspects instead of the image quality.
It's like judging a book by it's cover.
I've never seen that as an issue.
Here in POTN, at least, "sharing" is more than just sharing the images but also about sharing info and helping others to learn.
'Course, for those who prefer not to share something like Exif shooting info, well, to each their own, but that doesn't mean there is something "wrong" with making the Exif available, and it doesn't make people who glance at the Exif "sneaky" or "snooping". This is, after all, a forum that is about photography and photography gear and the use of that gear. It includes sections for sharing images, and posting images is a very useful part of many of our discussions, but so is sharing info and helping others!
