That doesn't seem like a good move in my opinion. There is a large and growing Spanish speaking community on steemit. People dont just meme in America. Each country seems to create memes that correlate with their culture making them difficult to understand sometimes.
9gag was never truly international but dmania might be able to achieve this.
Maybe Dmania should only accept languages that are used by very large amounts of people: English, Mandari, Arabic,Spanish, Hindi etc.
Or create a way to filter by language, that would also force users before posting to choose their respective language.
