Hi @cs
Our Community Feed accounts are automated mirrors of the Communities on the Newsmast app.
Our Communities are hand-curated using filters, follows, hashtags and mutes - by humans. You can't replicate it with hashtags alone, but we understand the frustration!
Our aim is to better help people find topical knowledge on the Fediverse, something we struggled with when we first joined.
If you want to see Communities firsthand, visit the Newsmast app on Apple App Store and Google Play.
