Ah. In the context of this thread, it's because I'm kind of a computer geek. I've done a lot of software beta test going back to Commodore 64 days, where the job is to figure out all the features without any documentation (because it hasn't been written yet, and you're actually helping to write it), and to try and break the software (so those bugs can be replicated and fixed before the release). So, my natural tendency is to snoop around and try to figure out how to do things and what all does what.
In the context of the Moon flags, it's just one of my many various and sundry interests. Learning about one thing leads to questions which lead to other things, all interwoven together. I tend to want to learn as much as possible about things which I find interesting, and I find a lot of things interesting, the more I learn about them.
