Ariel, I love the Boost Program. Some people talk down about it, but it's wonderful to have humans making decisions about content written by humans. I do think emotion and feeling can be a niche. A feeling or vibe within a publication can be a niche when properly cultivated. At least that's how I feel about the quality and content in The Interstitial. Thanks for this post and all you do to keep Medium running and growing. -R
