The way the term medium is used here really bothers me. For one, because I was taught that a medium is a <i>oneway</i> communication channel. Further more, because the plural media has an idiomatic meaning in English, that is the publishing industry. I find it Ironic that it&#x27;s in the name of the site, even, although I should judge the content by its merit. I don&#x27;t because it&#x27;s tl;dr and I got lost around the explanation of SVD (a link to wikipedia would be enough).
