A new feature in Epicyon is the hashtag swarm on the search screen.

I didn't want to have a "trending hashtags" or anything like that because it then encourages people to become fixated on whatever is at the top. As we can easily see in other social network systems, conflating popularity with importance - or trying to have an algorithm decide what is important - tends to result in bad outcomes, dubious economies selling "likes" or fake followers, and SEO-like activity. So instead the hashtag swarm just shows whatever hashtags are appearing in your inbox posts today, in alphabetical order. Each tag links to the list of posts which include it, and they can be liked or replied to.
