module OpenGraphHelper
# OpenGraph is in meta tags. First I thought it would bring problem if meta tags wouldn't change between page load.
# Thinking it through, it doesn't matter if open graph tags aren't changed between pages as it's needed by crawler that does full page load
# So the tags will always match the content.
# I doubt this will change in the future as turbolinks checks for crawlers and disable itself when it meets one.
