+## Intro
+
+For "power users" the traditional SPA is dead. If you're not universally rendering on the server, you're at risk of choking search engine visibility. As it stands, SEO and client-side rendering are not a match for SSR. Even though many search engines claim better SPA indexing, there are many caveats. **Server-side rendering matters: [JavaScript & SEO Backfire – A Hulu.com Case Study](https://www.elephate.com/blog/javascript-seo-backfire-hulu-com-case-study/)**

 It's made possible by our [PR to webpack](https://github.com/webpack/webpack/pull/5235) which built support for ```require.resolveWeak(`'./${page}`)```. Before it couldn't be dynamic--i.e. it supported one module, not a folder of modules.
 
-You no longer need to create a hash of all your universal or loadable components. You can frictionlessly support multiple components in one HoC as if imports weren't static. This seamingly small thing--we predict--will lead to universal rendering finally becoming commonplace. It's what a universal component for React is supposed to be.
+Dont forget to check out  [webpack-flush-chunks](https://github.com/faceyspacey/webpack-flush-chunks) - it provides the server with info about the render so it can deliver the right assets from the start. No additional async imports on first load. [It reduces time to interactive](https://developers.google.com/web/tools/lighthouse/audits/time-to-interactive)
 
-Of course, you also need [webpack-flush-chunks](https://github.com/faceyspacey/webpack-flush-chunks) to bring this together server-side. Ultimately that's the real foundation here and the most challenging part. Packages in the past like *React Loadable* did not address this aspect. They excelled at the SPA. In terms of universal rendering, they got you maybe 15% of the way by providing the module IDs rendered. There's a lot more than that.

-In the future both packages will be distilled into one product called `universal-render`--or ***"Universal"*** for short. The transition will be seamless. We're making this space as easy as possible for "power users" like yourself that prefer the *frameworkless* approach over the constraints of a framework like Next.js.
