I've published a new Micro.blog plugin called Lite YouTube which does one thing: finds YouTube links in posts and appends a lite-youtube-embed to the post. Example before and after below:

You can see it working on this post about The Last of Us or on this post with two videos.

Why did I do this instead of using YouTube shortcodes? Two reasons:

1. Shortcodes are great but what if I change where my site is hosted? Those links won't work any more
2. (This is the real reason) I will forget, I'm too lazy to do it, this is automatic.

You can install it from the plug-in directory and view the code on GitHub.
