Oh, that's the other thing about good data ideas. They are almost uniformly dumb.
If you feel really smart when you come up with a data idea. Sorry, buddy, I got bad news for you.
I've been working with data for so long. Often, it feels like there is nothing new under the sun. Just applying the basics, doing it on a bigger scale, and being insanely paranoid.
Occasionally, though, you will come across an idea so brilliant and simple that you are just blown away that it hasn't already been done in public before.
