At least in American English, the phrase "who cares" is not meant to be interpreted literally. It's not a question, but rather a (flippant) way of saying "I don't care" or "no one cares." Note that the poster in question expands on this and ends their post with, "I don't care what this dude does with his money and time." The people who do care about the article have upvoted it. Other than the ones who have commented, it doesn't matter who has found it interesting. The only thing that matters is that enough people have.
