1) learned some new html today

Looking at youtube blog, https://youtube-eng.googleblog.com/2018/08/control-your-360-videos-with-youtube.html

ran into the following code:

<!--[if IE]>
  <script type="text/javascript" 
    src="https://www.blogger.com/static/v1/jsbin/1277698886-ieretrofit.js"
  ></script>
<![endif]-->

There is no way this possibly runs!

a quick google search later: https://css-tricks.com/how-to-create-an-ie-only-stylesheet

Oh, - so there are other uses for <!--, 🆒

My recent work has me doing a lot of IE support since the userbase contains that marketshare. However it is the last concern since it is such a small userbase.

Death to IE, but pretty cool to learn some new html.

2) learned blogger.com meta tags for social twitter and facebook

<meta content='Your twitter info here' property='twitter:title' />
<meta content='Your facebook info here' property='og:title' />

3) rel=canonical

<link href='https://youtube-eng.googleblog.com/2018/08/control-your-360-videos-with-youtube.html' rel='canonical' />

4) rel=alternate

tell search engine, if someone is coming from a different language show different content. or if someone is coming from an rss+xml feed show different content 👍
