>It would be great to hear some thoughts and feedback

Not sure if this is the feedback you want... but:

  <meta property="og:image" content="/images/blog/feature/">

Your <meta> og:image is not an image.

  <img src=/images/logos/logo.svg alt=AirGradient width=160px>
  <img src=/images/logos/icon.svg alt=AirGradient width=40px>

You have <img> tags with width set to pixels but you can only specify units in CSS, not HTML.

Also you have loads of </li> tags with no start tag (duplicates?) and loads of other html errors. Yeah, I tested your page with a parser I am working on :D
