I am told (!) that Tumblr is one of the more immature platforms out there, especially in regards to feminism/gaming. Then again, it might just be that jug5 doesn't like Tumblr. I wouldn't know, really.
There's no reason to disregard a piece of writing because of the platform it's published on, especially considering the creators of Tumblr have no agenda and there's no barrier to entry. Would this piece suddenly become better if it were written on Medium?
I thought my comment was more relevant to yours than the OP's since you mentioned the frequently-cited claims against the platform. I meant to add to the discussion, not critique your post.
