While yours is a well thought out comment, from dealing extensively with web site latency for multiple sites, "bleeding edge" is often slower than "simple" or "old".
As others have pointed out, it's the 300kb of javascript from 10 different social widget and ad sites that slow down the page. Most research on this topic today emphasizes client-side latency, as in the code and structure of what your browser downloads and in what sequence. Client side latency generally consumes > 90% of the user visible latency. After all, light and packets can travel half-way around the world in just 60 milliseconds, yet this is talking about penalizing sites taking over 4 seconds to load.
TL; DR; You won't have to upgrade or buy lightning fast hosting. Just don't bloat down your page with dozens of third party js or tens/hundreds of poorly compressed images and you'll be fine!
