The vast majority of EXIF data is indeed pretty irrelevant to this purpose and machine-generated.  However, the Metadata Working Group specifically mentions the 'Description' tag, and increasingly cataloging and web upload programs use that, and so users are increasingly filling it in.  Sometimes the description generated by the photographer/creator are more accurate than those of the person who put the image on the web, especially when the web author leaves alt out :-(
