Is there some reference or website that explains what all the gobboldygook that's contained in the metadata means?
I can understand much of it, and obviously things like shutter speed, aperture, ISO, etc. are pretty self-explanatory. Even things like Flash Compulsory Did Not Fire lend themselves to common sense interpretations.
But some of the lines, like Original Subsecond Time, Unknown tag Tagnum 0x8830 = data ===> 2 or User Comment Hex (followed by a bunch of multiplication problems) make absolutely no sense.
There's obviously a reason for this stuff to be recorded. I'd just like to know what it means.

EXIF metadata standards specify the format for image and audio files to ensure compatibility between applications and devices that process image files. The standard and TAG information is informative for developers/programmers. It isn't intended to be anything other than gobbledygook to the average consumer. Some of it is obviously useful to photographers - camera settings - but the rest of it, less so.
If you want to dive into EXIF Metadata tags, you can read all about them in the latest specification:

That "Gobbledygook" contains a fair amount of technical information for image processing and determining the source of errors if needed. This data is also present in most multimedia files.
Besides the Exif data, there is also IPTC/XMP data that is used the international press organizations and others for capturing information about the photographer, descriptions of the scene, location, and rights granted in using the image. This "Gobbledygook" is added by the photographer and it can be helpful in protecting his/her rights to the image and that can be worth a significant amount of damages in certain circumstances.
