Anyone know what this information pertains too?
I put in my VIN and got all kinds of info but what the heck does it all mean / used for?

It appears to be a software update history for a particular VIN.

 

That site is used by GM tech's.On a lot of brand new vehicles, the factory workers are lazy and don't enter the calibration info for the car for a few months. So when a tech need to preprogram a BCM for a particualr vehicle, he can check this website to see if the info is there, otherwise he needs to get a VCI from engineering.
Its also useful to see what issues the new software will address.

 

Thought I’d resurrect this link, I went and checked my VIN and it doesn’t appear that I am due any updates, or at least there were no bulletins listed for my 07.
I’m about due an oil change and figured I'd check before I took it in, yesI take it to the dealer for the oil change I just don't trust the monkeys they have at the quickie lube places that and I don't want to deal with disposing of the waste oil and I can get them to rotate the tires and re-learn the TPMS
