Definitely dig the wake-up call at the end that you're just learning and interested in it. I think otherwise, a lot of people would take your word as gospel, since you're a high profile witness.
I have a hard time believing in these various wave theories. Humans LOVE patterns, and we're very good at convincing ourselves that they're all over the place. That being said -- large groups of people tend to operate in ways that allow macro-analysis of systems to be possible. From my own background in civil engineering, there are daily curves that define typical or expected peak hours and intensity of water usage. I'll admit that this is significantly more complicated and sentiment based, but it doesn't sound completely impossible.
Thanks for sharing. Here's hoping that Steem continues to gain in value!
