Imho it's boring because "active" is the default and works differently from reddit. It shows you active posts, as in posts that have a lot of new comments. This leads to some posts being on the front page for days.

The filter "hot" is supposed to be like reddit, but is currently broken on a lot of instances.

For the best experience I strongly recommend kbin.social since they have a working "hot" as their default giving you the most reddit-like experience out of all the instances I've tried.
