@jrovu I get what you're asking for, but I don't think either is available in any masto-if/client that Ive tried.
1. just posts (no boost/replies/mentions) and not hashtags
2. just hashtags no posts
I would strongly recommend #Mastodon team consider building this feature.
I have some generic, wide-ranging hashtags (#Music, #Python) - Most of this is noise to me, but occasionally I find great people I want to follow.
Most of the time, I'd like to JUST see a feed of the people I'm following - without seeing all the cruft.
Currently, that seems difficult, without explicitly adding everyone I follow to a list - tedious. Make sense?
