Consider changing how you define a smaller community
Browsing through the homepage today, the "Recommended smaller communities" section had six channels in it. None had less than 20 viewers and all had at least 3.5K followers. These are NOT small communities. I generally hang out in streams with 10-20 viewers at most and they generally have less than 1K followers. The streams in the section now may not be large, but, compared to the vast majority of channels on Twitch, they are HUGE. If the goal of this section is truly to promote small communities, you can do much better than this.
