What are some of your favourite custom MetaTags. I was given the opportunity to create the #gayblacksanta tag with my most recent post and I was smiling as I typed it out. You have your every day #science #books #videogames kind of tags (and of course these are important and useful). But then you have those special ones that are specific to a particular post. They're often one-off kind of tags and may not ever be used again based on their specificity. What are some of your favourites?
