TwitterCard meta tags are supposed to use the attributes "name" and "content".
OpenGraph tags use the attributes "property" and "content".

and not OpenGraph may fail to correctly detect the tags as they're under the wrong attributes.

weird values in href will cause base64 encoding to fail later down the
line, so let's make sure the value we're passing on is somewhat sane, or
at the very least a binary
