I see that blurry zoom transition effect all over the place. I suspect retina Macs don't do it, so designers keep doing it. Kinda reminds me that up until recently, Shopify used to only list Helvetica in their font-family, so Windows users saw Times New Roman. I see that stuff all the time coming from Mac-centric design firms.

^ I hesitated writing that, since it was all speculation, but then I clicked the link at the bottom saying "Hire me!" to see the designer's website and...

    html {
        font-family: "Avenir";
    }

No fallbacks whatsoever, so I'm seeing Times New Roman.
