The fact that OptinMonster is built with WordPress will never cease to fascinate me. Asked my dev team if we could make the static template library *in the app* more flexible so that we can more easily manage and test various configurations on the fly, without needing the dev team. In fact, what I actually said was, "Remember the Genesis Featured Posts widget? I want that - flexible widget areas. Or like Post Grid blocks." A week later, they've got the POC using Blocks and Patterns - flexible, but constrained enough to be always on brand - in a way that would let us test various layouts of the page to see which ones increase activation the most. Don't let anyone tell you WordPress is dying. If you know what to do with it, it's just getting started.
