Custom Tweaks for Jetpack by BarryCarlyon

Extras for WordPress Jetpack. Tested up to Jetpack 3.4.1

Jetpack automatically disables its Open Graph tags when there’s a known plugin that already adds Open Graph tags, which is good. Sometimes, though, you might want to use Jetpack’s version instead. Even if you disable the tags in the conflicting plugin, Jetpack won’t add Open Graph tags without being told to do so.
This is great for when you want to use the awesome WP SEO by Yoast plugin or others like All-in-One SEO, but, for whatever reason, would like to use Jetpack’s OG tags instead.

Always Use Open Graph with Jetpack
