I'd like to see #Pleroma or #Mastodon provide Filtered Lists, such that I can see posts from a list of people that include (or exclude) a particular term(s) (likely a particular hashtag). This would address this problem:

Without this, persons with varied interests can seem overly noisy (low signal-to-noise ratio) for potential followers that are interested in only one of their interests (or are actively disinterested in one of them --- HAH).
