It's just a list of posts that we tagged manually and then defined a URL endpoint for. We do that sometimes, but rarely enough that I can understand the confusion.
Keep in mind that we have a REPL over here and can make any link do anything!

Thanks for the response, I guess it's rare enough that it was the first time I remember seeing it so it stuck out to me.
