I’ve been thinking I might make one more small enhancement: adding metadata to the HTML for link previews (eg when you share a link to your blog on twitter etc). I’ll look into that a bit.
I was helped by an interesting chat with someone who was using a link shortener on twitter which I suggested he reconsider due to privacy concerns.
He was doing so for aesthetic reasons only and went into it in some depth for which I’m grateful because he’s pointed me to how to add the metadata for previews. In the end he realised using a link shortener didn’t do what he wanted and has stopped using them. Win win!
