I wish i could look it up but the site seems to be down. I've seen it before. But it sounds like something I experienced before. You struggle to try to understand what this "new" thing is that's hot and it doesn't seem new to you at all. It frustrates you as you see other people talking about it excitedly and you feel like you're missing something. In my experience that's all it is. It's not new but a different spin on a long established and understood concept.
