Using EXIF data for design/marketing decisions

This isn't the best of DigitalRev TV's videos (I like the Pro Photographer, Cheap Camera ones better). But it made me think.

First: They've removed some modes compared to an earlier model. Too many can be confusing, so nothing wrong with that, but how to decide which ones to keep? You could scour the Internet for images taken with the camera model you're interested in and check the EXIF data.

And on sites were users who upload photos state their gender and age, you can look at that too.
